I ran across some unique css class attribute:value pairings in HTML tags. It looks like some custom JavaScript is interpreting this, but I have never seen this before. I saw this on http://www.woothemes.com/flexslider/ (you have to view source to see the following)
<pre class="brush: js; toolbar: false; gutter: false;">
Is this a custom library or javascript application that can be freely used?
As you can read in the source, it’s the http://alexgorbatchev.com/SyntaxHighlighter that uses these classes.
