Implement Github-Flavored Markdown on Markdown Code Blocks

[alkrauss48]

This site uses marked for handling the processing of markdown, and Github-Flavored Markdown is a default feature (or it should be default, per the docs)

For example, if you add this block of code to your presentation:

```php
echo('foo bar');
$x = false;
\```

(but without that leading slash at the end; couldn't figure out how to display the code block backticks otherwise 😂) Then you will get the following HTML:

<pre><code class="language-php">echo('foo bar');
$x = false;
</code></pre>

Which looks like this:

It looks like it's doing something related to formatting, but so far only adding that language- class to the surrounding element. Without doing more research, I assume we need to:

• Find a front-end tool that takes that code and styles it, or
• Breaks that down into more classes, and then allows us to write styles to highlight the code ourselves

That's where I'm at with this. Research the rest, explore, and implement what you can!
