<p>mdBook uses <a href="https://highlightjs.org">Highlight.js</a> with a custom theme

|

<p>Automatic language detection has been turned off, so you will probably want to

specify the programming language you use like this:</p>

<pre><code class="language-markdown">```rust

<h2 id="custom-theme"><a class="header" href="#custom-theme">Custom theme</a></h2>
|

|
|
<p>Like the rest of the theme, the files used for syntax highlighting can be
|
||
|
|
overridden with your own.</p>
|
||
|
|
<ul>
|
||
|
|
<li><em><strong>highlight.js</strong></em> normally you shouldn't have to overwrite this file, unless
|
||
|
|
you want to use a more recent version.</li>
|
||
|
|
<li><em><strong>highlight.css</strong></em> theme used by highlight.js for syntax highlighting.</li>
|
||
|
|
</ul>
|
||
|
|
<p>If you want to use another theme for <code>highlight.js</code> download it from their
|
||
|
|
website, or make it yourself, rename it to <code>highlight.css</code> and put it in
|
||
|
|
the <code>theme</code> folder of your book.</p>
|
||
|
|
<p>Now your theme will be used instead of the default theme.</p>
|
||
|
|
<h2 id="improve-default-theme"><a class="header" href="#improve-default-theme">Improve default theme</a></h2>
|
||
|
|
<p>If you think the default theme doesn't look quite right for a specific language,
|
||
|
|
or could be improved, feel free to <a href="https://github.com/rust-lang/mdBook/issues">submit a new
|
||
|
|
issue</a> explaining what you
|
||
|
|
have in mind and I will take a look at it.</p>
|
||
|
|
<p>You could also create a pull-request with the proposed improvements.</p>
|
||
|
|
<p>Overall the theme should be light and sober, without too many flashy colors.</p>
