+# crossdomain.xml
+
+A cross-domain policy file is an XML document that grants a web client—such as
+Adobe Flash Player, Adobe Reader, etc., permission to handle data across
+multiple domains. When a client hosts content from a particular source domain
+and that content makes requests directed towards a domain other than its own,
+the remote domain would need to host a cross-domain policy file that grants
+access to the source domain, allowing the client to continue with the
+transaction. Policy files grant read access to data, permit a client to include
+custom headers in cross-domain requests, and are also used with sockets to
+grant permissions for socket-based connections.
+
+For full details, check out Adobe's article about the [cross-domain policy file
+specification](http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html).

+
+# The CSS
+
+The HTML5 Boilerplate starting CSS includes:
+
+* [Normalize.css](https://github.com/necolas/normalize.css).
+* Useful HTML5 Boilerplate defaults.
+* Common helpers.
+* Placeholder media queries.
+* Print styles.
+
+This starting CSS does not rely on the presence of conditional classnames,
+conditional style sheets, or Modernizr. It is ready to use whatever your
+development preferences happen to be.
+
+
+## Normalize.css
+
+Normalize.css is a modern, HTML5-ready alternative to CSS resets. It contains
+extensive inline documentation. Please refer to the [Normalize.css
+project](http://necolas.github.com/normalize.css/) for more information.
+
+
+## HTML5 Boilerplate defaults
+
+This project includes a handful of base styles that build upon Normalize.css.
+These include:
+
+* Basic typography settings to provide improved text readability by default.
+* Protection against unwanted `text-shadow` during text highlighting.
+* Tweaks to default image alignment, fieldsets, and textareas.
+* A pretty Chrome Frame prompt.
+
+You are free to modify or add to these base styles as your project requires.
+
+
+## Common helpers
+
+#### `.ir`
+
+Add the `.ir` class to any element you are applying image-replacement to. When
+replacing an element's content with an image, make sure to also set a specific
+`background-image: url(pathtoimage.png);`, `width`, and `height` so that your
+replacement image appears.
+
+#### `.hidden`
+
+Add the `.hidden` class to any elements that you want to hide from all
+presentations, including screen readers. It could be an element that will be
+populated later with JavaScript or an element you will hide with JavaScript. Do
+not use this for SEO keyword stuffing. That is just not cool.
+
+#### `.visuallyhidden`
+
+Add the `.visuallyhidden` class to hide text from browsers but make it
+available for screen readers. You can use this to hide text that is specific to
+screen readers but that other users should not see. [About invisible
+content](http://www.webaim.org/techniques/css/invisiblecontent/), [Hiding
+content for
+accessibility](http://snook.ca/archives/html_and_css/hiding-content-for-accessibility),
+[HTML5 Boilerplate
+issue/research](https://github.com/h5bp/html5-boilerplate/issues/194/).
+
+#### `.invisible`
+
+Add the `.invisible` class to any element you want to hide without affecting
+layout. When you use `display: none` an element is effectively removed from the
+layout. But in some cases you want the element to simply be invisible while
+remaining in the flow and not affecting the positioning of surrounding
+content.
+
+#### `.clearfix`
+
+Adding `.clearfix` to an element will ensure that it always fully contains its
+floated children. There have been many variants of the clearfix hack over the
+years, and there are other hacks that can also help you to contain floated
+children, but the HTML5 Boilerplate currently uses the [micro
+clearfix](http://nicolasgallagher.com/micro-clearfix-hack/).
+
+
+## Media Queries
+
+The boilerplate makes it easy to get started with a "Mobile First" and
+[Responsive Web
+Design](http://www.alistapart.com/articles/responsive-web-design/) approach to
+development. But it's worth remembering that there are [no silver
+bullets](http://www.cloudfour.com/css-media-query-for-mobile-is-fools-gold/).
+
+We include a placeholder Media Queries to build up your mobile styles for wider
+viewports and high-resolution displays. It's recommended that you adapt these
+Media Queries based on the content of your site rather than mirroring the fixed
+dimensions of specific devices.
+
+If you do not want to take a "Mobile First" approach, you can simply edit or
+remove these placeholder Media Queries. One possibility would be to work from
+wide viewports down and use `max-width` MQs instead, e.g., `@media only screen
+and (max-width: 480px)`.
+
+Take a look into the [Mobile
+Boilerplate](https://github.com/h5bp/mobile-boilerplate) for features that are
+useful when developing mobile wep apps.
+
+
+## Print styles
+
+* Print styles are inlined to [reduce the number of page
+  requests](http://www.phpied.com/delay-loading-your-print-css/).
+* We strip all background colors and change the font color to dark gray and
+  remove text-shadow. This is meant to help save printer ink.
+* Anchors do not need colors to indicate they are linked. They are underlined
+  to indicate so.
+* Anchors and Abbreviations are expanded to indicate where users reading the
+  printed page can refer to.
+* But we do not want to show link text for image replaced elements (given that
+  they are primarily images).
+
+### Paged media styles
+
+* Paged media is supported only in a [few
+  browsers](http://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28Cascading_Style_Sheets%29#Grammar_and_rules).
+* Paged media support means browsers would know how to interpret instructions
+  on breaking content into pages and on orphans/widows.
+* We use `page-break-inside: avoid;` to prevent an image and table row from
+  being split into two different pages, so use the same `page-break-inside:
+  avoid;` for that as well.
+* Headings should always appear with the text they are titles for. So, we
+  ensure headings never appear in a different page than the text they describe
+  by using `page-break-after: avoid;`.
+* We also apply a default margin for the page specified in `cm`.
+* We do not want [orphans and
+  widows](http://en.wikipedia.org/wiki/Widows_and_orphans) to appear on pages
+  you print. So, by defining `orphans: 3` and `widows: 3` you define the minimal
+  number of words that every line should contain.

+
+# Extend and customise HTML5 Boilerplate
+
+Here is some useful advice for how you can make your project with HTML5
+Boilerplate even better. We don't want to include it all by default, as not
+everything fits with everyone's needs.
+
+
+## DNS prefetching
+
+In short, DNS Prefetching is a method of informing the browser of domain names
+referenced on a site so that the client can resolve the DNS for those hosts,
+cache them, and when it comes time to use them, have a faster turn around on
+the request.
+
+### Implicit prefetches
+
+There is a lot of prefetching done for you automatically by the browser. When
+the browser encounters an anchor in your html that does not share the same
+domain name as the current location the browser requests, from the client OS,
+the IP address for this new domain. The client first checks its cache and
+then, lacking a cached copy, makes a request from a DNS server. These requests
+happen in the background and are not meant to block the rendering of the
+page.
+
+The goal of this is that when the foreign IP address is finally needed it will
+already be in the client cache and will not block the loading of the foreign
+content. Less requests result in faster page load times. The perception of this
+is increased on a mobile platform where DNS latency can be greater.
+
+#### Disable implicit prefetching
+
+```html
+<meta http-equiv="x-dns-prefetch-control" content="off">
+```
+
+Even with X-DNS-Prefetch-Control meta tag (or http header) browsers will still
+prefetch any explicit dns-prefetch links.
+
+**_WARNING:_** THIS MAY MAKE YOUR SITE SLOWER IF YOU RELY ON RESOURCES FROM
+FOREIGN DOMAINS.
+
+### Explicit prefetches
+
+Typically the browser only scans the HTML for foreign domains. If you have
+resources that are outside of your HTML (a javascript request to a remote
+server or a CDN that hosts content that may not be present on every page of
+your site, for example) then you can queue up a domain name to be prefetched.
+
+```html
+<link rel="dns-prefetch" href="//example.com">
+<link rel="dns-prefetch" href="//ajax.googleapis.com">
+```
+
+You can use as many of these as you need, but it's best if they are all
+immediately after the [Meta
+Charset](https://developer.mozilla.org/en/HTML/Element/meta#attr-charset)
+element (which should go right at the top of the `head`), so the browser can
+act on them ASAP.
+
+#### Common Prefetch Links
+
+Amazon S3:
+
+```html
+<link rel="dns-prefetch" href="//s3.amazonaws.com">
+```
+
+Google APIs:
+
+```html
+<link rel="dns-prefetch" href="//ajax.googleapis.com">
+```
+
+Microsoft Ajax Content Delivery Network:
+
+```html
+<link rel="dns-prefetch" href="//ajax.microsoft.com">
+<link rel="dns-prefetch" href="//ajax.aspnetcdn.com">
+```
+
+### Browser support for DNS prefetching
+
+Chrome, Firefox 3.5+, Safari 5+, Opera (Unknown), IE 9 (called "Pre-resolution"
+on blogs.msdn.com)
+
+### Further reading about DNS prefetching

+* http://dayofjs.com/videos/22158462/web-browsers_alex-russel
+
+
+## Search
+
+### Direct search spiders to your sitemap
+
+[Learn how to make a sitemap](http://www.sitemaps.org/protocol.php)
+
+```html
+<link rel="sitemap" type="application/xml" title="Sitemap" href="/sitemap.xml">
+```
+
+### Hide pages from search engines
+
+According to Heather Champ, former community manager at Flickr, you should not
+allow search engines to index your "Contact Us" or "Complaints" page if you
+value your sanity. This is an HTML-centric way of achieving that.
+
+```html
+<meta name="robots" content="noindex">
+```
+
+**_WARNING:_** DO NOT INCLUDE ON PAGES THAT SHOULD APPEAR IN SEARCH ENGINES.
+
+### Firefox and IE Search Plugins
+
+Sites with in-site search functionality should be strongly considered for a
+browser search plugin. A "search plugin" is an XML file which defines how your
+plugin behaves in the browser. [How to make a browser search
+plugin](http://www.google.com/search?ie=UTF-8&q=how+to+make+browser+search+plugin).
+
+```html
+<link rel="search" title="" type="application/opensearchdescription+xml" href="">
+```
+
+
+## Internet Explorer
+
+### Prompt users to switch to "Desktop Mode" in IE10 Metro
+
+IE10 does not support plugins, such as Flash, in Metro mode. If your site
+requires plugins, you can let users know that via the X-UA-Compatible meta
+element, which will prompt them to switch to Desktop Mode.
+
+```html
+<meta http-equiv="X-UA-Compatible" content="requiresActiveX=true">
+```
+
+Here's what it looks like alongside H5BP's default X-UA-Compatible values:
+
+```html
+<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1,requiresActiveX=true">
+```
+
+You can find more information in [Microsoft's IEBlog post about prompting for
+plugin use in IE10 Metro
+Mode](http://blogs.msdn.com/b/ie/archive/2012/01/31/web-sites-and-a-plug-in-free-web.aspx).
+
+### IE Pinned Sites (IE9+)
+
+Enabling your application for pinning will allow IE9 users to add it to their
+Windows Taskbar and Start Menu. This comes with a range of new tools that you
+can easily configure with the elements below. See more [documentation on IE9
+Pinned Sites](http://msdn.microsoft.com/en-us/library/gg131029.aspx).
+
+### Name the Pinned Site for Windows
+
+Without this rule, Windows will use the page title as the name for your
+application.
+
+```html
+<meta name="application-name" content="Sample Title">
+```
+
+### Give your Pinned Site a tooltip
+
+You know — a tooltip. A little textbox that appears when the user holds their
+mouse over your Pinned Site's icon.
+
+```html
+<meta name="msapplication-tooltip" content="A description of what this site does.">
+```
+
+### Set a default page for your Pinned Site
+
+If the site should go to a specific URL when it is pinned (such as the
+homepage), enter it here. One idea is to send it to a special URL so you can
+track the number of pinned users, like so:
+`http://www.example.com/index.html?pinned=true`
+
+```html
+<meta name="msapplication-starturl" content="http://www.example.com/index.html?pinned=true">
+```
+
+### Recolor IE's controls manually for a Pinned Site
+
+IE9+ will automatically use the overall color of your Pinned Site's favicon to
+shade its browser buttons. UNLESS you give it another color here. Only use
+named colors (`red`) or hex colors (`#ff0000`).
+
+```html
+<meta name="msapplication-navbutton-color" content="#ff0000">
+```
+
+### Manually set the window size of a Pinned Site
+
+If the site should open at a certain window size once pinned, you can specify
+the dimensions here. It only supports static pixel dimensions. 800x600
+minimum.
+
+```html
+<meta name="msapplication-window" content="width=800;height=600">
+```
+
+### Jump List "Tasks" for Pinned Sites
+
+Add Jump List Tasks that will appear when the Pinned Site's icon gets a
+right-click. Each Task goes to the specified URL, and gets its own mini icon
+(essentially a favicon, a 16x16 .ICO). You can add as many of these as you
+need.
+
+```html
+<meta name="msapplication-task" content="name=Task 1;action-uri=http://host/Page1.html;icon-uri=http://host/icon1.ico">
+<meta name="msapplication-task" content="name=Task 2;action-uri=http://microsoft.com/Page2.html;icon-uri=http://host/icon2.ico">
+```
+
+### (Windows 8) High quality visuals for Pinned Sites
+
+Windows 8 adds the ability for you to provide a PNG tile image and specify the
+tile's background color. [Full details on the IE
+blog](http://blogs.msdn.com/b/ie/archive/2012/06/08/high-quality-visuals-for-pinned-sites-in-windows-8.aspx).
+
+* Create a 144x144 image of your site icon, filling all of the canvas, and
+  using a transparent background.
+* Save this image as a 32-bit PNG and optimize it without reducing
+  colour-depth. It can be named whatever you want (e.g. `metro-tile.png`).
+* To reference the tile and its color, add the HTML `meta` elements described
+  in the IE Blog post.
+
+### (Windows 8) Badges for Pinned Sites
+
+IE10 will poll an XML document for badge information to display on your app's
+tile in the Start screen. The user will be able to receive these badge updates
+even when your app isn't actively running. The badge's value can be a number,
+or one of a predefined list of glyphs.

+### Suppress IE6 image toolbar
+
+Kill IE6's pop-up-on-mouseover toolbar for images that can interfere with
+certain designs and be pretty distracting in general.

+
+
+## Social Networks
+
+### Facebook Open Graph data
+
+You can control the information that Facebook and others display when users
+share your site. Below are just the most basic data points you might need. For
+specific content types (including "website"), see [Facebook's built-in Open
+Graph content
+templates](https://developers.facebook.com/docs/opengraph/objects/builtin/).
+Take full advantage of Facebook's support for complex data and activity by
+following the [Open Graph
+tutorial](https://developers.facebook.com/docs/opengraph/tutorial/).
+
+```html
+<meta property="og:title" content="">
+<meta property="og:description" content="">
+<meta property="og:image" content="">
+```
+
+### Twitter Cards
+
+Twitter provides a snippet specification that serves a similar purpose to Open
+Graph. In fact, Twitter will use Open Graph when Cards is not available. Note
+that, as of this writing, Twitter requires that app developers activate Cards
+on a per-domain basis. You can read more about the various snippet formats
+and application process in the [official Twitter Cards
+documentation](https://dev.twitter.com/docs/cards).
+
+```html
+<meta name="twitter:card" content="summary">
+<meta name="twitter:site" content="@site_account">
+<meta name="twitter:creator" content="@individual_account">
+<meta name="twitter:url" content="http://www.example.com/path/to/page.html">

+## URLs
+
+### Canonical URL
+
+Signal to search engines and others "Use this URL for this page!" Useful when
+parameters after a `#` or `?` is used to control the display state of a page.

+## App Stores
+
+### Install a Chrome Web Store app
+
+Users can install a Chrome app directly from your website, as long as the app
+and site have been associated via Google's Webmaster Tools. Read more on
+[Chrome Web Store's Inline Installation
+docs](https://developers.google.com/chrome/web-store/docs/inline_installation).

+
+## Google Analytics augments
+
+### More tracking settings
+
+The [optimized Google Analytics
+snippet](http://mathiasbynens.be/notes/async-analytics-snippet) included with
+HTML5 Boilerplate includes something like this:
+
+```js
+var _gaq = [['_setAccount', 'UA-XXXXX-X'], ['_trackPageview']];
+```
+
+In case you need more settings, just extend the array literal instead of
+[`.push()`ing to the
+array](http://mathiasbynens.be/notes/async-analytics-snippet#dont-push-it)
+afterwards:
+
+```js
+var _gaq = [['_setAccount', 'UA-XXXXX-X'], ['_trackPageview'], ['_setAllowAnchor', true]];
+```
+
+### Anonymize IP addresses
+
+In some countries, no personal data may be transferred outside jurisdictions
+that do not have similarly strict laws (i.e. from Germany to outside the EU).
+Thus a webmaster using the Google Analytics script may have to ensure that no
+personal (trackable) data is transferred to the US. You can do that with [the
+`_gat.anonymizeIp`
+option](http://code.google.com/apis/analytics/docs/gaJS/gaJSApi_gat.html#_gat._anonymizeIp).
+In use it looks like this:
+
+```js
+var _gaq = [['_setAccount', 'UA-XXXXX-X'], ['_gat._anonymizeIp'], ['_trackPageview']];
+```
+
+### Track jQuery AJAX requests in Google Analytics
+
+An article by @JangoSteve explains how to [track jQuery AJAX requests in Google
+Analytics](http://www.alfajango.com/blog/track-jquery-ajax-requests-in-google-analytics/).
+
+Add this to `plugins.js`:
+
+```js
+/*
+ * Log all jQuery AJAX requests to Google Analytics
+ * See: http://www.alfajango.com/blog/track-jquery-ajax-requests-in-google-analytics/
+ */
+if (typeof _gaq !== "undefined" && _gaq !== null) {
+    $(document).ajaxSend(function(event, xhr, settings){
+        _gaq.push(['_trackPageview', settings.url]);
+    });
+}
+```
+
+### Track JavaScript errors in Google Analytics
+
+Add this function after `_gaq` is defined:
+
+```js
+(function(window){
+    var undefined,
+        link = function (href) {
+            var a = window.document.createElement('a');
+            a.href = href;
+            return a;
+        };
+    window.onerror = function (message, file, row) {
+        var host = link(file).hostname;
+        _gaq.push([
+            '_trackEvent',
+            (host == window.location.hostname || host == undefined || host == '' ? '' : 'external ') + 'error',
+            message, file + ' LINE: ' + row, undefined, undefined, true
+        ]);
+    };
+}(window));
+```
+
+### Track page scroll
+
+Add this function after `_gaq` is defined:
+
+```js
+$(function(){
+    var isDuplicateScrollEvent,
+        scrollTimeStart = new Date,
+        $window = $(window),
+        $document = $(document),
+        scrollPercent;
+
+    $window.scroll(function() {
+        scrollPercent = Math.round(100 * ($window.height() + $window.scrollTop())/$document.height());
+        if (scrollPercent > 90 && !isDuplicateScrollEvent) { //page scrolled to 90%
+            isDuplicateScrollEvent = 1;
+            _gaq.push(['_trackEvent', 'scroll',
+                'Window: ' + $window.height() + 'px; Document: ' + $document.height() + 'px; Time: ' + Math.round((new Date - scrollTimeStart )/1000,1) + 's',
+                undefined, undefined, true
+            ]);
+        }
+    });
+});
+```
+
+
+## Miscellaneous
+
+* Use [HTML5
+  polyfills](https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-browser-Polyfills).
+
+* Use [Microformats](http://microformats.org/wiki/Main_Page) (via

+# Frequently asked questions
+
+### Why is the URL for jQuery without "http"?
+
+This is an intentional use of [protocol-relative
+URLs](http://paulirish.com/2010/the-protocol-relative-url/)
+
+**N.B.** Using a protocol-relative URL for files that exist on a CDN is
+problematic when you try to view your local files directly in the browser. The
+browser will attempt to fetch the file from your local file system. We
+recommend that you use a local server to test your pages (or Dropbox). This can
+be done using Python by running `python -m SimpleHTTPServer` from your local
+directory, using Ruby by installing and running
+[asdf](https://rubygems.org/gems/asdf), and by installing any one of XAMPP,
+MAMP, or WAMP.
+
+
+### Why don't you automatically load the latest version of jQuery from the Google CDN?
+
+1. The latest version of jQuery may not be compatible with the existing
+   plugins/code on the site. Version updating should be an intentional
+   decision.
+2. The latest version has a very short `max-age=3600` compares to the specific
+   version of `max-age=31536000`, which means you won't get the benefits of
+   long-term caching.
+
+
+### Why is the Google Analytics code at the bottom? Google recommends it be placed the `head`.
+
+The advantage to placing it in the `head` is that you will track a user's
+pageview even if they leave the page before it has been fully loaded. However,
+putting the code at the bottom keeps all the scripts together and reinforces
+that scripts at the bottom are the right move.
+
+
+### How can I integrate [Twitter Bootstrap](http://twitter.github.com/bootstrap/) with HTML5 Boilerplate?
+
+You can use [Initializr](http://initializr.com) to create a custom build that
+includes HTML5 Boilerplate with Twitter Bootstrap.
+
+Read more about how [HTML5 Boilerplate and Twitter Bootstrap complement each
+other](http://www.quora.com/Is-Bootstrap-a-complement-OR-an-alternative-to-HTML5-Boilerplate-or-viceversa/answer/Nicolas-Gallagher).
+
+
+### How do I prevent phone numbers looking twice as large and having a Skype highlight?
+
+If this is occurring, it is because a user has the Skype browser extension
+installed.
+
+Use the following CSS to prevent Skype from formatting the numbers on your
+page:
+
+```css
+span.skype_pnh_container {
+    display: none !important;
+}
+
+span.skype_pnh_print_container {
+    display: inline !important;
+}
+```
+
+
+### Do I need to upgrade my sites each time a new version of HTML5 Boilerplate is released?
+
+No. You don't normally replace the foundations of a house once it has been
+built. There is nothing stopping you from trying to work in the latest changes
+but you'll have to assess the costs/benefits of doing so.
+
+
+### Where can I get help for support questions?
+
+Please ask for help on
+[StackOverflow](http://stackoverflow.com/questions/tagged/html5boilerplate).

+
+# .htaccess
+
+In Apache HTTP server, `.htaccess` (hypertext access) is the configuration file
+that allows for web server configuration. HTML5 Boilerplate includes a number
+of best practice server rules for making web pages fast and secure, these rules
+can be applied in the `.htaccess` file.
+
+**First, you'll want to have these modules enabled for optimum performance:**
+
+* `mod_setenvif.c` (setenvif_module)
+* `mod_headers.c` (headers_module)
+* `mod_deflate.c` (deflate_module)
+* `mod_filter.c` (filter_module)
+* `mod_expires.c` (expires_module)
+* `mod_rewrite.c` (rewrite_module)
+
+
+## On Windows
+
+You've got a couple of options that depend on how you installed Apache.
+
+1. **WampServer**. This is by far the simplest option. If you have installed
+   WampServer just click on the icon in the task bar, hover over the Apache
+   section in the menu that comes up and then hover over the modules section.
+   You will be presented with a list of modules. Simply click on a module name
+   to enable it (or disable it if it is already enabled). A check mark next to
+   a module indicates that it is enabled. WampServer will automatically restart
+   the Apache service after you enable a module.
+
+2. **Manually editing `httpd.conf`**. This assumes that you have manually
+   installed Apache. You will need to locate the `httpd.conf` file which is
+   normally in the `conf` folder in the folder where you installed Apache (for
+   example `C:\apache\conf\httpd.conf`). Open up this file in a text editor. Near
+   the top (after a bunch of comments) you will see a long list of modules. Check
+   to make sure that the modules listed above are not commented out. If they
+   are, go ahead and uncomment them and restart Apache.
+
+That's it, you're done!
+
+
+## On Linux
+
+These instructions should work on any distribution where `apt-get` has been
+used to install Apache.
+
+1. Open up a terminal and type the following command. Enter your password when
+   prompted.
+
+    `sudo a2enmod setenvif headers deflate filter expires rewrite include`
+
+1. Restart apache by using the following command so the new configuration takes
+   effect.
+
+    `sudo /etc/init.d/apache2 restart`
+
+That's it, you're done!
+
+
+## On Mac
+
+1. **MAMP PRO**. On the main screen, click the `Apache` tab and ensure that all
+   the required modules listed above are 'checked', indicating they are
+   enabled.
+
+2. **MAMP**. Locate the `httpd.conf` file, which is typically found in
+   `/Applications/MAMP/conf/apache/httpd.conf`. Open the file in a text editor
+   and uncomment all of the required modules listed above. Once you have done so,
+   reset MAMP.
+
+3. **XAMPP**. Follow the same steps as for MAMP, but look for `httpd.conf` in
+   `/Applications/XAMPP/etc/httpd.conf`.
+
+
+## Security
+
+Do not turn off your ServerSignature (i.e., the `Server:` HTTP header). Serious
+attackers can use other kinds of fingerprinting methods to figure out the
+actual server and components running behind a port. Instead, as a site owner,
+you should keep track of what's listening on ports on hosts that you control.
+Run a periodic scanner to make sure nothing suspicious is running on a host you
+control, and use the ServerSignature to determine if this is the web server and
+version that you expect.
+
+
+## Performance
+
+### Configure ETags
+
+```apache
+FileETag None
+```
+
+Entity tags (ETags) is a mechanism that web servers and browsers use to
+determine whether the component in the browser's cache matches the one on the
+origin server. (An "entity" is another word for "component": images, scripts,
+stylesheets, etc.) ETags were added to provide a mechanism for validating
+entities that is more flexible than the last-modified date. An `ETag` is a
+string that uniquely identifies a specific version of a component. The only
+format constraints are that the string be quoted. The origin server specifies
+the component's `ETag` using the `ETag` response header.
+
+```http
+HTTP/1.1 200 OK
+Last-Modified: Tue, 12 Dec 2006 03:03:59 GMT
+ETag: "10c24bc-4ab-457e1c1f"
+Content-Length: 12195
+```
+
+Later, if the browser has to validate a component, it uses the `If-None-Match`
+header to pass the `ETag` back to the origin server. If the ETags match, a 304
+status code is returned reducing the response by 12195 bytes for this
+example.
+
+```http
+GET /i/yahoo.gif HTTP/1.1
+Host: us.yimg.com
+If-Modified-Since: Tue, 12 Dec 2006 03:03:59 GMT
+If-None-Match: "10c24bc-4ab-457e1c1f"
+HTTP/1.1 304 Not Modified
+```
+
+The problem with ETags is that they typically are constructed using attributes
+that make them unique to a specific server hosting a site. ETags won't match
+when a browser gets the original component from one server and later tries to
+validate that component on a different server, a situation that is all too
+common on web sites that use a cluster of servers to handle requests. By
+default, both Apache and IIS embed data in the ETag that dramatically reduces
+the odds of the validity test succeeding on web sites with multiple servers.
+
+The ETag format for Apache 1.3 and 2.x is inode-size-timestamp. Although a
+given file may reside in the same directory across multiple servers, and have
+the same file size, permissions, timestamp, etc., its inode is different from
+one server to the next.
+
+IIS 5.0 and 6.0 have a similar issue with ETags. The format for ETags on IIS is
+Filetimestamp:ChangeNumber. A ChangeNumber is a counter used to track
+configuration changes to IIS. It's unlikely that the ChangeNumber is the same
+across all IIS servers behind a web site.
+
+The end result is ETags generated by Apache and IIS for the exact same
+component won't match from one server to another. If the ETags don't match, the
+user doesn't receive the small, fast 304 response that ETags were designed for;
+instead, they'll get a normal 200 response along with all the data for the
+component. If you host your web site on just one server, this isn't a problem.
+But if you have multiple servers hosting your web site, and you're using Apache
+or IIS with the default ETag configuration, your users are getting slower
+pages, your servers have a higher load, you're consuming greater bandwidth, and
+proxies aren't caching your content efficiently. Even if your components have a
+far future Expires header, a conditional GET request is still made whenever the
+user hits Reload or Refresh.
+
+If you're not taking advantage of the flexible validation model that ETags
+provide, it's better to just remove the ETag altogether. The Last-Modified
+header validates based on the component's timestamp. And removing the ETag
+reduces the size of the HTTP headers in both the response and subsequent
+requests. This Microsoft Support article describes how to remove ETags. In
+Apache, this is done by simply adding the above line to your Apache
+configuration file.
+
+
+### Gzip Components
+
+Compression reduces response times by reducing the size of the HTTP response.
+
+Starting with HTTP/1.1, web clients indicate support for compression with the
+Accept-Encoding header in the HTTP request.
+
+```
+Accept-Encoding: gzip, deflate
+```
+
+If the web server sees this header in the request, it may compress the response
+using one of the methods listed by the client. The web server notifies the web
+client of this via the Content-Encoding header in the response.
+
+```
+Content-Encoding: gzip
+```
+
+Gzip is the most popular and effective compression method at this time. It was
+developed by the GNU project and standardized by RFC 1952. The only other
+compression format you're likely to see is deflate, but it's less effective and
+less popular.
+
+Gzipping generally reduces the response size by about 70%. Approximately 90% of
+today's Internet traffic travels through browsers that claim to support gzip.
+If you use Apache, the module configuring gzip depends on your version: Apache
+1.3 uses `mod_gzip` while Apache 2.x uses `mod_deflate`.
+
+There are known issues with browsers and proxies that may cause a mismatch in
+what the browser expects and what it receives with regard to compressed
+content. Fortunately, these edge cases are dwindling as the use of older
+browsers drops off. The Apache modules help out by adding appropriate Vary
+response headers automatically.
+
+Servers choose what to gzip based on file type, but are typically too limited
+in what they decide to compress. Most web sites gzip their HTML documents. It's
+also worthwhile to gzip your scripts and stylesheets, but many web sites miss
+this opportunity. In fact, it's worthwhile to compress any text response
+including XML and JSON. Image and PDF files should not be gzipped because they
+are already compressed. Trying to gzip them not only wastes CPU but can
+potentially increase file sizes.
+
+Gzipping as many appropriate file types as possible is an easy way to reduce
+page weight and accelerate the user experience.
+
+
+### Cache busting
+
+A first-time visitor to your page may have to make several HTTP requests, but
+by using the Expires header you make those components cacheable. This avoids
+unnecessary HTTP requests on subsequent page views. Expires headers are most
+often used with images, but they should be used on all components including
+scripts, stylesheets, etc.
+
+Traditionally, if you use a far future Expires header you have to change the
+component's filename whenever the component changes.
+
+The H5BP `.htaccess` has built-in filename cache busting. To use it, uncomment
+the relevant lines in the `.htaccess` file.
+
+Doing so will route all requests for `/path/filename.20120101.ext` to
+`/path/filename.ext`. To use this, just add a time-stamp number (or your own
+numbered versioning system) into your resource filenames in your HTML source
+whenever you update those resources.
+
+#### Example:
+
+```html
+<script src="/js/myscript.20120305.js"></script>
+<script src="/js/jqueryplugin.45.js"></script>
+<link rel="stylesheet" href="css/somestyle.49559939932.css">
+<link rel="stylesheet" href="css/anotherstyle.2.css">
+```
+
+**N.B. You do not have to rename the resource on the filesystem.** All you have
+to do is add the timestamp number to the filename in your HTML source. The
+`.htaccess` directive will serve up the proper file.
+
+Traditional cache busting involved adding a query string to the end of your
+JavaScript or CSS filename whenever you updated it.
+
+```html
+<script src="/js/all.js?v=12"></script>
+```
+
+However, as [Steve Souders](http://stevesouders.com/) explains in [*Revving
+Filenames: don’t use
+querystring*](http://www.stevesouders.com/blog/2008/08/23/revving-filenames-dont-use-querystring/),
+the query string approach is not always reliable for clients behind a Squid
+Proxy Server.
+
+
+## Trailing slash redirects
+
+Trailing slash redirects can be done by adding one of the options below in `.htaccess`.
+
+### Option 1
+Rewrite `domain.com/foo` -> `domain.com/foo/`.
+
+```apache
+RewriteCond %{REQUEST_FILENAME} !-f
+RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/|#(.*))$
+RewriteRule ^(.*)$ $1/ [R=301,L]
+```
+
+### Option 2
+Rewrite `domain.com/foo/` -> `domain.com/foo`
+
+```apache
+RewriteRule ^(.*)/$ $1 [R=301,L]
+```
+
+Here are some tips to show you how to integrate the rewrite rules with
+different CMS tools. There are four areas you need to look out for:
+
+### 1. Keep a backup
+
+If you use trailing slash redirects on an existing site, always keep a backup
+of your `.htaccess` and test thoroughly on your staging server before using it on
+a production server.
+
+### 2. Don't replace existing rules, merge
+
+For example, if you use CodeIgniter you may have existing URL rewrite rules like:
+
+```apache
+RewriteCond %{REQUEST_FILENAME} !-f
+RewriteCond %{REQUEST_FILENAME} !-d
+RewriteRule ^(.*)$ index.php/$1
+```
+
+Merge the above with H5BP rules below:
+
+```apache
+RewriteCond %{REQUEST_FILENAME} !-f
+RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/|#(.*))$
+RewriteRule ^(.*)$ $1/ [R=301,L]
+```
+
+### 3. Be careful of the order
+
+Make sure you test thoroughly in your staging environment. For the above
+example, the order is add trailing slash first, and add your existing rule
+after:
+
+```apache
+# this adds trailing slash
+RewriteCond %{REQUEST_FILENAME} !-f
+RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/|#(.*))$
+RewriteRule ^(.*)$ $1/ [R=301,L]
+
+# this gets rid of index.php
+RewriteCond %{REQUEST_FILENAME} !-f
+RewriteCond %{REQUEST_FILENAME} !-d
+RewriteRule ^(.*)$ index.php/$1
+```
+
+### 4. Double-check `RewriteBase` path is correct
+
+Make sure your `RewriteBase` path points to the correct location and sits above
+any rewrite rules. This usually happens to those have WordPress and ran the
+auto install. For instance, if you have a site at `example.com/blog`, your
+RewriteBase may look like:
+
+```apache
+RewriteBase /blog/
+```
+
+If you already have a working RewriteBase, keep that and don't remove it.

+
+# The HTML
+
+## Conditional `html` classes
+
+A series of IE conditional comments apply the relevant IE-specific classes to
+the `html` tag. This provides one method of specifying CSS fixes for specific
+legacy versions of IE. While you may or may not choose to use this technique in
+your project code, HTML5 Boilerplate's default CSS does not rely on it.
+
+When using the conditional classes technique, applying classes to the `html`
+element has several benefits:
+
+* It avoids a [file blocking
+  issue](http://webforscher.wordpress.com/2010/05/20/ie-6-slowing-down-ie-8/)
+  discovered by Stoyan Stefanov and Markus Leptien.
+* It avoids the need for an empty comment that also fixes the above issue.
+* CMSes like WordPress and Drupal use the body class more heavily. This makes
+  integrating there a touch simpler.
+* It still validates as HTML5.
+* It uses the same element as Modernizr (and Dojo). That feels nice.
+* It can improve the clarity of code in multi-developer teams.
+
+
+## The `no-js` class
+
+Allows you to more easily explicitly add custom styles when JavaScript is
+disabled (`no-js`) or enabled (`js`). More here: [Avoiding the
+FOUC](http://paulirish.com/2009/avoiding-the-fouc-v3/).
+
+
+## The order of meta tags, and `<title>`
+
+As recommended by [the HTML5
+spec](http://www.whatwg.org/specs/web-apps/current-work/complete/semantics.html#charset)
+(4.2.5.5 Specifying the document's character encoding), add your charset
+declaration early (before any ASCII art ;) to avoid a potential
+[encoding-related security
+issue](http://code.google.com/p/doctype/wiki/ArticleUtf7) in IE. It should come
+in the first [1024
+bytes](http://www.whatwg.org/specs/web-apps/current-work/multipage/semantics.html#charset).
+
+The charset should also come before the `<title>` tag, due to [potential XSS
+vectors](http://code.google.com/p/doctype-mirror/wiki/ArticleUtf7).
+
+The meta tag for compatibility mode [needs to be before all elements except
+title and meta](http://h5bp.com/f "Defining Document Compatibility - MSDN").
+And that same meta tag can only be invoked for Google Chrome Frame if it is
+within the [first 1024
+bytes](http://code.google.com/p/chromium/issues/detail?id=23003).
+
+
+## X-UA-Compatible
+
+This makes sure the latest version of IE is used in versions of IE that contain
+multiple rendering engines. Even if a site visitor is using IE8 or IE9, it's
+possible that they're not using the latest rendering engine their browser
+contains. To fix this, use:
+
+```html
+<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
+```
+
+The `meta` tag tells the IE rendering engine two things:
+
+1. It should use the latest, or edge, version of the IE rendering environment
+2. If already installed, it should use the Google Chrome Frame rendering
+   engine.
+
+This `meta` tag ensures that anyone browsing your site in IE is treated to the
+best possible user experience that their browser can offer.
+
+This line breaks validation, and the Google Chrome Frame part won't work inside
+a conditional comment. To avoid these edge case issues it is recommended that
+you **remove this line and use the `.htaccess`** (or other server config)
+to send these headers instead. You also might want to read [Validating:
+X-UA-Compatible](http://groups.google.com/group/html5boilerplate/browse_thread/thread/6d1b6b152aca8ed2).
+
+If you are serving your site on a non-standard port, you will need to set this
+header on the server-side. This is because the IE preference option 'Display
+intranet sites in Compatibility View' is checked by default.
+
+
+## Mobile viewport
+
+There are a few different options that you can use with the [`viewport` meta
+tag](https://docs.google.com/present/view?id=dkx3qtm_22dxsrgcf4 "Viewport and
+Media Queries - The Complete Idiot's Guide"). You can find out more in [the
+Apple developer docs](http://j.mp/mobileviewport). HTML5 Boilerplate comes with
+a simple setup that strikes a good balance for general use cases.
+
+```html
+<meta name="viewport" content="width=device-width">
+```
+
+## Favicons and Touch Icons
+
+The shortcut icons should be put in the root directory of your site. HTML5
+Boilerplate comes with a default set of icons (include favicon and Apple Touch
+Icons) that you can use as a baseline to create your own.
+
+If your site or icons are in a sub-directory, you will need to reference the
+icons using `link` elements placed in the HTML `head` of your document.
+
+For a comprehensive overview, please read [Everything you always wanted to know
+about touch icons](http://mathiasbynens.be/notes/touch-icons) by Mathias
+Bynens.
+
+
+## Modernizr
+
+HTML5 Boilerplate uses a custom build of Modernizr.
+
+[Modernizr](http://modernizr.com) is a JavaScript library which adds classes to
+the `html` element based on the results of feature test and which ensures that
+all browsers can make use of HTML5 elements (as it includes the HTML5 Shiv).
+This allows you to target parts of your CSS and JavaScript based on the
+features supported by a browser.
+
+In general, in order to keep page load times to a minimum, it's best to call
+any JavaScript at the end of the page because if a script is slow to load
+from an external server it may cause the whole page to hang. That said, the
+Modernizr script *needs* to run *before* the browser begins rendering the page,
+so that browsers lacking support for some of the new HTML5 elements are able to
+handle them properly. Therefore the Modernizr script is the only JavaScript
+file synchronously loaded at the top of the document.
+
+
+## The content area
+
+The central part of the boilerplate template is pretty much empty. This is
+intentional, in order to make the boilerplate suitable for both web page and
+web app development.
+
+### Google Chrome Frame
+
+The main content area of the boilerplate includes a prompt to install Chrome
+Frame (which no longer requires administrative rights) for users of IE 6. If
+you intended to support IE 6, then you should remove the snippet of code.
+
+### Google CDN for jQuery
+
+The Google CDN version of the jQuery JavaScript library is referenced towards
+the bottom of the page using a protocol-independent path (read more about this
+in the [FAQ](faq.md)). A local fallback of jQuery is included for rare instances
+when the CDN version might not be available, and to facilitate offline
+development.
+
+Regardless of which JavaScript library you choose to use, it is well worth the
+time and effort to look up and reference the Google CDN (Content Delivery
+Network) version. Your users may already have this version cached in their
+browsers, and Google's CDN is likely to deliver the asset faster than your
+server.
+
+### Google Analytics Tracking Code
+
+Finally, an optimized version of the latest Google Analytics tracking code is
+included. Google recommends that this script be placed at the top of the page.
+Factors to consider: if you place this script at the top of the page, you’ll be
+able to count users who don’t fully load the page, and you’ll incur the max
+number of simultaneous connections of the browser.
+
+Further information:
+
+* [Optimizing the asynchronous Google Analytics
+  snippet](http://mathiasbynens.be/notes/async-analytics-snippet).
+* [Tracking Site Activity - Google
+  Analytics](http://code.google.com/apis/analytics/docs/tracking/asyncTracking.html).

+
+## .gitignore
+
+HTML5 Boilerplate includes a basic project-level `.gitignore`. This should
+primarily be used to avoid certain project-level files and directories from
+being kept under source control. Different development-environments will
+benefit from different collections of ignores.
+
+OS-specific and editor-specific files should be ignored using a "global
+ignore" that applies to all repositories on your system.
+
+For example, add the following to your `~/.gitconfig`, where the `.gitignore`
+in your HOME directory contains the files and directories you'd like to
+globally ignore:
+
+```gitignore
+[core]
+    excludesfile = ~/.gitignore
+```
+
+* More on global ignores: http://help.github.com/ignore-files/

+
+# Usage
+
+Once you have cloned or downloaded HTML5 Boilerplate, creating a site or app
+usually involves the following:
+
+1. Set up the basic structure of the site.
+2. Add some content, style, and functionality.
+3. Run your site locally to see how it looks.
+4. (Optionally run a build script to automate the optimization of your site -
+   e.g. [ant build script](https://github.com/h5bp/ant-build-script) or [node
+   build script](https://github.com/h5bp/node-build-script)).
+5. Deploy your site.
+
+
+## Basic structure
+
+A basic HTML5 Boilerplate site initially looks something like this:
+
+```
+.
+├── css
+│   ├── main.css
+│   └── normalize.css
+├── doc
+├── img
+├── js
+│   ├── main.js
+│   ├── plugins.js
+│   └── vendor
+│       ├── jquery.min.js
+│       └── modernizr.min.js
+├── .htaccess
+├── 404.html
+├── index.html
+├── humans.txt
+├── robots.txt
+├── crossdomain.xml
+├── favicon.ico
+└── [apple-touch-icons]
+```
+
+What follows is a general overview of each major part and how to use them.
+
+### css
+
+This directory should contain all your project's CSS files. It includes some
+initial CSS to help get you started from a solid foundation. [About the
+CSS](css.md).
+
+### doc
+
+This directory contains all the HTML5 Boilerplate documentation. You can use it
+as the location and basis for your own project's documentation.
+
+### js
+
+This directory should contain all your project's JS files. Libraries, plugins,
+and custom code can all be included here. It includes some initial JS to help
+get you started. [About the JavaScript](js.md).
+
+### .htaccess
+
+The default web server config is for Apache. [About the .htaccess](htaccess.md).
+
+Host your site on a server other than Apache? You're likely to find the
+corresponding configuration file in our [server configs
+repo](https://github.com/h5bp/server-configs). If you cannot find a
+configuration file for your setup, please consider contributing one so that
+others can benefit too.
+
+### 404.html
+
+A helpful custom 404 to get you started.
+
+### index.html
+
+This is the default HTML skeleton that should form the basis of all pages on
+your site. If you are using a server-side templating framework, then you will
+need to integrate this starting HTML with your setup.
+
+Make sure that you update the URLs for the referenced CSS and JavaScript if you
+modify the directory structure at all.
+
+If you are using Google Analytics, make sure that you edit the corresponding
+snippet at the bottom to include your analytics ID.
+
+### humans.txt
+
+Edit this file to include the team that worked on your site/app, and the
+technology powering it.
+
+### robots.txt
+
+Edit this file to include any pages you need hidden from search engines.
+
+### crossdomain.xml
+
+A template for working with cross-domain requests. [About
+crossdomain.xml](crossdomain.md).
+
+### icons
+
+Replace the default `favicon.ico` and apple touch icons with your own. You
+might want to check out Hans Christian's handy [HTML5 Boilerplate Favicon and
+Apple Touch Icon
+PSD-Template](http://drublic.de/blog/html5-boilerplate-favicons-psd-template/).
