Tab Content Script is a standards compliant, 2 level content script. Click on a tab, and additional content appears beneath it while contracting any previously open content. The script uses CSS to control all of its appearance, and lets you enter plain HTML for the tab contents, making customization a breeze. Set which tab should initially be shown when the page first loads, and the color of each tab and its content can easily be changed via a custom HTML attribute. Script works in IE5 and NS6 above, degrading well with the rest.
