Test code

Syntax highlighting implemented for Tumblr, based on Dan Webb’s CodeHighlighter

JavaScript Example

/*
This script detects external links in a page
and attaches a behaviour to them so they open
in a external window.
*/

function initialiseLinks() {
    if (document.getElementsByTagName) {
        var links = document.getElementsByTagName("A");
        for (var i = 0; i < links.length; i++) {
            if (links[i].href.indexOf("http:")==0) {
                // if the links URL starts with http: then we assume it's an external link
                links[i].onclick = function() {
                    window.open(this.href);
                    return false; // stop normal link behaviour
                }
            }
        }
    }
}

window.onload = initialiseLinks();

CSS Example

.javascript  .comment {
	color : green; /* ffbgffg */
}
