Customization

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.

The theme provides several ways to customize from including a custom stylesheet and JavaScript code to overriding the individual templates.

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 src/main/paradox directory:

mkdir -p src/main/paradox/assets
touch src/main/paradox/assets/custom.css

Then, add the following line to your build.sbt:

paradoxMaterialTheme in Compile ~= {
  _.withCustomStylesheet("assets/custom.css")
}

Start typing your changes in your additional stylesheet file – you can see them after saving and running paradox.

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 src/main/paradox directory:

mkdir -p src/main/paradox/assets
touch src/main/paradox/assets/custom.js

Then, add the following line to your build.sbt:

paradoxMaterialTheme in Compile ~= {
  _.withCustomJavaScript("assets/custom.js")
}

Extending the theme

If you want to alter the HTML source (e.g. add or remove some part), you can extend the theme. Paradox allowing a way to modify a theme without forking and changing the main theme. By default, files can be added in src/main/paradox/_template to override those provided by the theme.

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 theme is as follows:

.
├── assets
│   ├── images                     # Images and icons
│   ├── javascripts                # JavaScript
│   └── stylesheets                # Stylesheets
├── partials
│   ├── footer.st                  # Page footer
│   ├── header.st                  # Page header
│   ├── nav.st                     # Main navigation
│   ├── poweredby.st               # Powered-by footer message
│   ├── search.st                  # Search box
│   ├── social.st                  # Social links
│   ├── source.st                  # Repository information
│   └── toc.st                     # Table of contents
└── page.st                        # Page base template

Overriding partials

In order to override the footer, we can replace the footer.st partial with our own partial. To do this, create the file partials/footer.st in the theme directory. Paradox will now use the new partial when rendering the theme. This can be done with any file.
