Request: Theme Customization per code block

Add support for attribute controlling what theme/style the code snippet should show in. As well as a language tag for specifying what language it is. The theme attribute could be set to the current theme unless anything else is set.

<pre><code language="cs" theme="dracula">
using system.net

namespace myApp {
	int myapp = new App();
	myapp.isAwesome();
}
</code></pre>

Every feature - no, but this one looks like something that can be accepted for me.

You can already do half of this with class:

<pre><code class="cs">...</code></pre>
