# Customization
|
||
|
||
## A great starting point
|
||
|
||
Project documentation is as diverse as the projects themselves and the Material
|
||
theme is a good starting point for making it look great. However, as you write
|
||
your documentation, you may reach a point where some small adjustments are
|
||
necessary to preserve the desired style.
|
||
|
||
## Adding assets
|
||
|
||
[MkDocs][1] provides several ways to interfere with themes. In order to make a
|
||
few tweaks to an existing theme, you can just add your stylesheets and
|
||
JavaScript files to the `docs` directory.
|
||
|
||
[1]: https://www.mkdocs.org
|
||
|
||
### Additional stylesheets
|
||
|
||
If you want to tweak some colors or change the spacing of certain elements,
|
||
you can do this in a separate stylesheet. The easiest way is by creating a
|
||
new stylesheet file in your `docs` directory:
|
||
|
||
``` sh
|
||
mkdir docs/stylesheets
|
||
touch docs/stylesheets/extra.css
|
||
```
|
||
|
||
Then, add the following line to your `mkdocs.yml`:
|
||
|
||
``` yaml
|
||
extra_css:
|
||
- 'stylesheets/extra.css'
|
||
```
|
||
|
||
Spin up the development server with `mkdocs serve` and start typing your
|
||
changes in your additional stylesheet file – you can see them instantly after
|
||
saving, as the MkDocs development server implements live reloading.
|
||
|
||
### Additional JavaScript
|
||
|
||
The same is true for additional JavaScript. If you want to integrate another
|
||
syntax highlighter or add some custom logic to your theme, create a new
|
||
JavaScript file in your `docs` directory:
|
||
|
||
``` sh
|
||
mkdir docs/javascripts
|
||
touch docs/javascripts/extra.js
|
||
```
|
||
|
||
Then, add the following line to your `mkdocs.yml`:
|
||
|
||
``` yaml
|
||
extra_javascript:
|
||
- 'javascripts/extra.js'
|
||
```
|
||
|
||
Further assistance can be found in the [MkDocs documentation][2].

||

||

|
||
|
||
## Extending the theme
|
||
|
||
If you want to alter the HTML source (e.g. add or remove some part), you can
|
||
extend the theme. From version 0.16 on MkDocs implements [theme extension][3],
|
||
an easy way to override parts of a theme without forking and changing the
|
||
main theme.
|
||
|
||
[3]: https://www.mkdocs.org/user-guide/styling-your-docs/#using-the-theme-custom_dir
|
||
|
||
### Setup and theme structure
|
||
|
||
Reference the Material theme as usual in your `mkdocs.yml`, and create a
|
||
new folder for overrides, e.g. `theme`, which you reference using `custom_dir`:
|
||
|
||
``` yaml
|
||
theme:
|
||
name: 'material'
|
||
custom_dir: 'theme'
|
||
```
|
||
|
||
!!! warning "Theme extension prerequisites"
|
||
|
||
As the `custom_dir` variable is used for the theme extension process, the
|
||
Material theme needs to be installed via `pip` and referenced with the
|
||
`name` parameter in your `mkdocs.yml`.
|
||
|
||
The structure in the theme directory must mirror the directory structure of the
|
||
original theme, as any file in the theme directory will replace the file with
|
||
the same name which is part of the original theme. Besides, further assets
|
||
may also be put in the theme directory.
|
||
|
||
The directory layout of the Material theme is as follows:
|
||
|
||
``` sh
|
||
.
|
||
├─ assets/
|
||
│ ├─ images/ # Images and icons
|
||
│ ├─ javascripts/ # JavaScript
|
||
│ └─ stylesheets/ # Stylesheets
|
||
├─ partials/
|
||
│ ├─ integrations/ # 3rd-party integrations
|
||
│ ├─ language/ # Localized languages
|
||
│ ├─ footer.html # Footer bar
|
||
│ ├─ header.html # Header bar
|
||
│ ├─ hero.html # Hero teaser
|
||
│ ├─ language.html # Localized labels
|
||
│ ├─ nav-item.html # Main navigation item
|
||
│ ├─ nav.html # Main navigation
|
||
│ ├─ search.html # Search box
|
||
│ ├─ social.html # Social links
|
||
│ ├─ source.html # Repository information
|
||
│ ├─ tabs-item.html # Tabs navigation item
|
||
│ ├─ tabs.html # Tabs navigation
|
||
│ ├─ toc-item.html # Table of contents item
|
||
│ └─ toc.html # Table of contents
|
||
├─ 404.html # 404 error page
|
||
├─ base.html # Base template
|
||
└─ main.html # Default page
|
||
```
|
||
|
||
### Overriding partials
|
||
|
||
In order to override the footer, we can replace the `footer.html` partial with
|
||
our own partial. To do this, create the file `partials/footer.html` in the
|
||
theme directory. MkDocs will now use the new partial when rendering the theme.
|
||
This can be done with any file.
|
||
|
||
### Overriding template blocks
|
||
|
||
Besides overriding partials, one can also override so called template blocks,
|
||
which are defined inside the Material theme and wrap specific features. To
|
||
override a template block, create a `main.html` inside the theme directory and
|
||
define the block, e.g.:
|
||
|
||
``` jinja
|
||
{% extends "base.html" %}
|
||
|
||
{% block htmltitle %}
|
||
<title>Lorem ipsum dolor sit amet</title>
|
||
{% endblock %}
|
||
```
|
||
|
||
The Material theme provides the following template blocks:
|
||
|
||
| Block name | Wrapped contents |
|
||
| ------------ | ----------------------------------------------- |
|
||
| `analytics` | Wraps the Google Analytics integration |
|
||
| `content` | Wraps the main content |
|
||
| `disqus` | Wraps the disqus integration |
|
||
| `extrahead` | Empty block to define additional meta tags |
|
||
| `fonts` | Wraps the webfont definitions |
|
||
| `footer` | Wraps the footer with navigation and copyright |
|
||
| `header` | Wraps the fixed header bar |
|
||
| `hero` | Wraps the hero teaser |
|
||
| `htmltitle` | Wraps the `<title>` tag |
|
||
| `libs` | Wraps the JavaScript libraries, e.g. Modernizr |
|
||
| `scripts` | Wraps the JavaScript application logic |
|
||
| `source` | Wraps the linked source files |
|
||
| `site_meta` | Wraps the meta tags in the document head |
|
||
| `site_nav` | Wraps the site navigation and table of contents |
|
||
| `styles` | Wraps the stylesheets (also extra sources) |
|
||

|
||
|
||
## Theme development
|
||
|
||
The Material theme uses [Webpack][5] as a build tool to leverage modern web
|
||
technologies like [Babel][6] and [SASS][7]. If you want to make more fundamental
|
||
changes, it may be necessary to make the adjustments directly in the source of
|
||
the Material theme and recompile it. This is fairly easy.
|
||
|
||
[5]: https://webpack.js.org/
|
||
[6]: https://babeljs.io
|
||
[7]: http://sass-lang.com
|
||
|
||
### Environment setup
|
||
|
||
In order to start development on the Material theme, a [Node.js][8] version of
|
||
at least 8 is required. First, clone the repository:
|
||
|
||
``` sh
|
||
git clone https://github.com/squidfunk/mkdocs-material
|
||
```
|
||
|
||
Next, all dependencies need to be installed, which is done with:
|
||
|
||
``` sh
|
||
cd mkdocs-material
|
||
pip install -r requirements.txt
|
||
npm install
|
||
```
|
||
|
||
[8]: https://nodejs.org
|
||
|
||
### Development mode
|
||
|
||
The development server can be started with:
|
||
|
||
``` sh
|
||
npm run watch
|
||
```
|
||
|
||
This will also start the MkDocs development server which will monitor changes
|
||
on assets, templates and documentation. Point your browser to
|
||
[localhost:8000][9] and you should see this documentation in front of you.
|
||
|
||
For example, changing the color palette is as simple as changing the
|
||
`$md-color-primary` and `$md-color-accent` variables in
|
||
`src/assets/stylesheets/_config.scss`:
|
||
|
||
``` css
|
||
$md-color-primary: $clr-red-400;
|
||
$md-color-accent: $clr-teal-a700;
|
||
```
|
||
|
||
!!! warning "Automatically generated files"
|
||
|
||
Never make any changes in the `material` directory, as the contents of this
|
||
directory are automatically generated from the `src` directory and will be
|
||
overridden when the theme is built.
|
||
|
||
[9]: http://localhost:8000
|
||
|
||
### Build process
|
||
|
||
When you've finished making your changes, you can build the theme by invoking:
|
||
|
||
``` sh
|
||
npm run build
|
||
```
|
||
|
||
This triggers the production-level compilation and minification of all
|
||
stylesheets and JavaScript sources. When the command exits, the final theme is
|
||
located in the `material` directory. Add the `theme_dir` variable pointing to
|
||
the aforementioned directory in your original `mkdocs.yml`.
|
||
|
||
Now you can run `mkdocs build` and you should see your documentation with your
|
||
changes to the original Material theme.
