SleekTabs is a PHP class which eases the process of creating tabbed interfaces in HTML. Basically put, if you want a tab system (like on Properties/Inspector-styl e dialogues on the desktop) for a bit of content on your web page, SleekTabs automates this process. Just give SleekTabs the names of your tabs, the URLs and customise the styles if you want, then just let ST do the rest!
