Mega menu CSS fixes - can be done in 15 minutes!

Some minor changes to an existing mega menu. Shouldn't take you more than 15 minutes!! Please refer to attached PDF and to this website to see the lateral menu in action: [login to view URL] Your CSS code should be clean and reutilise (as much as possible) the already existing classes so we can understand and maintain in the future. You should only work on the style sheet and not the HTML, since it is generated by a PHP and we don't intend to modify it. Should be tested on all browsers (IE 7/8/9, Chrome, Safari, Firefox) and at least degrade gracefully!
