For more information on how template blocks work, consult the [Django documentation](https://docs.djangoproject.com/en/stable/ref/templates/builtins/#block).
### layout.html
Path: `base/layout.html`
NetBox provides a base template to ensure a consistent user experience, which plugins can extend with their own content. This is a general-purpose template that can be used when none of the function-specific templates below are suitable.
#### Blocks
| Name | Required | Description |
|-----------|----------|----------------------------|
| `header` | - | Page header |
| `tabs` | - | Horizontal navigation tabs |
| `modals` | - | Bootstrap 5 modal elements |
#### Example
An example of a plugin template which extends `layout.html` is included below.
```jinja2
{% extends 'base/layout.html' %}
{% block header %}
My Custom Header
{% endblock header %}
{% block content %}
{{ some_plugin_context_var }}
{% endblock content %}
```
The first line of the template instructs Django to extend the NetBox base template and inject our custom content within its `content` block.
!!! note
Django renders templates with its own custom [template language](https://docs.djangoproject.com/en/stable/topics/templates/#the-django-template-language). This is very similar to Jinja2, however there are some important distinctions of which authors should be aware. Be sure to familiarize yourself with Django's template language before attempting to create new templates.
