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! SleekTabs has a built-in Ajax feature - just make a simple page which provides the HTML you want put inside the content area (excluding headers etc.) and tell ST where to find it! With full Ajax functionality, plus a fallback for those without Ajax or without JavaScript, SleekTabs adds that extra Ajax touch to any page while optionally retaining backwards-compatibility for those with JavaScript off, screen readers or old browsers. SleekTabs is free software/open source under the BSD Licence. See the licence header in the sleektabs.php file for more information.
