Changing style sheets

This page links to two style sheets. First to the usual js.css which I use throughout all my sites, then to a special style sheet for these test pages. You'll notice that some tags have a different colour than usual.

<link rel="stylesheet" href="../js.css">
<link rel="stylesheet" href="specialstyle.css">

This is element x.

x is document.styleSheets[1].

Test x.deleteRule(0)
Test x.insertRule('pre {border: 1px solid #000000}',x.cssRules.length);

Test x.addRule('pre','border: 1px solid #000000');
Test x.removeRule(0);
