Highlight JS

Highlight JS is a script I am using to give blocks of code a nicer format. Here is the website

Within <code> attributes you write the corresponding class you want to use (ie: <code class="HTML">). Although the site mentions it can automatically detect it.

Javascript

document.addEventListener('contextmenu', event => event.preventDefault());
CSS
h1 {
    text-transform: uppercase;
    color: #251d16;
    border-bottom-style: groove;
    }
HTML
Unfortunately it doesn't work well with HTML tags. I had to use "& l t " for left side tag to break it so it could work.
