Project Description:
Hi, I get many errors w3c on a development site.
Errors are based in the menu. There is a problem with the navigation menu.
It's a ul/li navigation which contains some divs inside to build a scrollbar for one of the sections.
I can post the URL to check later via private messages.
I need a css/html/jquery PRO to fix this with me, without accessing the development server, I will be available via email and skype messages.
