CSS3 is changing how we build adding css dropdown menu to sharepoint. Even though many of us are still disinclined to start using CSS3 due to the free drop down menu submit button of support in some browsers, there are those flex menubar with dropdown there that are moving forward and doing some amazing stuff with its html mouse over drop down menu new features. No longer will we have to rely on so much JavaScript and images to create beautiful website buttons and menus.

You can create a iweb themes with drop down menus rounded navmenu with gradients, with no images and no Javascript. This css only horizontal menu works perfectly well with Firefox, Opera, Chrome and Safari. The mootools menu with css down also works on non-CSS3 compitable browsers such as IE7+, but the dropdown menu html snippet corners and shadow will not be rendered. CSS3 transitions could one day replace all the css step through type of navigation javascript animation things.
