Styling Jekyll language specific code blocks
While inspecting the markup of some syntax highlighted code blocks I noticed something I hadn’t before, language-lexer classes:
<div class="language-css highlighter-rouge">
<pre class="highlight">
<code>.foo { color: red; }</code>
</pre>
</div>This extra hook1 on the <div> element opens up some interesting styling possibilities. A fun use case for this is styling code blocks to look like terminal windows. Assign terminal2 as the language/lexer like so:
```terminal
```Add the following Sass to your site’s stylesheet:
$terminal-window-height: 30px;
.language-terminal {
position: relative;
margin-bottom: 1.5em;
padding: calc(#{$terminal-window-height} + 1em) 1em 1em;
border: 1px solid $border-color;
border-radius: $border-radius;
box-shadow: 0 0.25em 1em rgba($base-color, 0.25);
background-color: $base-color;
&::before {
content: "\2022 \2022 \2022";
position: absolute;
top: 0;
left: 0;
margin: 0;
padding: (0.5 * $terminal-window-height) 0;
background: mix($base-color, #fff, 25%);
color: mix($base-color, #fff, 50%);
font-size: (2 * $terminal-window-height);
line-height: 0;
text-indent: (0.5 * $terminal-window-height);
}
.highlight {
margin: 0;
padding: 0;
background-color: initial;
color: #fff;
}
}And you’ll get something that looks like this:
[15:34:01] Finished 'site' after 2.18 min
[15:34:01] Starting 'copy:site'...
[15:34:06] Finished 'copy:site' after 4.8 s
[15:34:06] Finished 'build:site' after 2.33 min
[15:34:06] Starting 'reload'...
[BS] Reloading Browsers...
[15:34:06] Finished 'reload' after 5.22 msThis isn’t limited to language-terminal, and can be applied to any of the other languages and lexers supported by Rouge.

Apparently this was added into Kramdown a year ago. :neutral_face: Who knew?

↩terminalandconsoleare aliases forshell_sessionand can be used interchangeably when assigning a language for syntax highlighting.
