CSS dropdown/flyout menu

I need a CSS menu created for a website with a top navigation. Currently the top navigation are images with rollover effects and i need this functionality to stay the same (however, if the top navigation needs to be re-coded in a simpler or more practical way to fit with the project then i am not opposed to doing so.) Right now the rollovers are just Javascript from dreamweaver. In the "About Us" link, i need a CSS (CLEAN CODE) dropdown menu linking to 3 other pages. The pages are: Our Servers ([login to view URL]) Our Datacenter ([login to view URL]) Our Network Center ([login to view URL]) In the "Services" link, i need a CSS (CLEAN CODE) dropdown menu linking to 2 other pages. The pages are: Web Hosting ([login to view URL]) Domain Names ([login to view URL]) In the "Support/FAQ" link, i need a CSS (CLEAN CODE) dropdown menu linking to 2 other pages. The pages are: Forums ([login to view URL]) Live Chat ([login to view URL]) Submit Ticket ([login to view URL]) Email Us (a mailto: link to davatechco AT davatech DotCom) I did a mockup of what I want the menu to look like. It's actually functional but what I want is clean CSS code - no javascript. All of the styles must follow this style guide. If you need specific HEX values and font colors, sizes, etc, please just contact me. Here is the site mockup: <[login to view URL]> Here is the menu mockup: <[login to view URL]> ## Deliverables I need the menu fully functional within the mockup given <[login to view URL]> I will need all the code, all the files, and the final result in a ZIP file that i can simply upload to the client's site. ## Platform I need this to be tested and functional on all major browsers (IE, Mozilla and Firefox, Opera, Safari, Netscape)
