JavaScript Syntax Highlighter

How to use it

Add the file syntax.min.js to the end of your code and it will automatically highlight every <code> tag that you have in your page. Or use the defer attribute:

<script src="syntax.min.js" defer></script>

The script will create <spam> tag for every reserved word, variable, methods and numbers so you can target them with CSS.

code {
  font-family: Consolas,"courier new";
  color: #EEE;
  background-color: #333;
  padding: 2px;
  font-size: 105%;
  display: block;
  white-space: pre;
  counter-reset: line;
}

code > div {
  counter-increment: line;
  display: block;
  min-height: 1em;
}

code > div::before {
  content: counter(line) '\A0';
  display: inline-block;
  width: 4ch;
  text-align: left;
  -webkit-select: none;
  color: #666;
}

.reserved {
  font-weight: bold;
  color: #55C;
}

.methods {
  font-weight: bold;
  color: green;
}

.variable {
  color: orange;
}

.comment {
