Goal:
Create a menu widget that does not require any javascript, extremely lightweight, very fast, soley based
on CSS, compatible with FireFox and Chrome.
Issues:
May have some rendering issues in some versions of IE, sorry :-)
Instruments:
css file
html with specific menu format
jQuery-ui library - optional if you want to use your own images/colors
Implementation Details:
HTML:
<div id="header">
<div id="header_Menubar">
<ul class="linkList0 ui-tabs-nav ui-helper-reset ui-helper-clearfix ui-widget-header ui-corner-all">
<li class="first more ui-state-default ui-corner-top ui-tabs-selected"><a title="Home" href="/Home">Home</a>

Also some CSS for global settings that will affect this menu, you of course will have some other styling, but included it here so you can see how/why some css properties were set here:
/* Neutralize styling:
Elements we want to clean out entirely: */
html, body
{
margin: 0;
padding: 0;
font: 62.5%/120% Verdana, Arial, Helvetica, sans-serif;
}
/* Neutralize styling:
Elements with a vertical margin: */
h1, h2, h3, h4, h5, h6, p, pre,
blockquote, ul, ol, dl, address {
margin: 0; /* most browsers set some default value that is not shared by all browsers */
padding: 0; /* some borowsers default padding, set to 0 for all */
}
/* Apply left margin:
Only to the few elements that need it: */
li, dd, blockquote {
margin-left: 1em;
}
