Yet another implementation of a graphic button with overlaid CSS styled text. Degrades differently, but still gracefully I think, in older browsers. I'm suggesting this for the techniques document, not to fuel further debate on graphical text. I'm hoping others will suggest still further variations, in addition to those already suggested by Bob and Kynn. See http://astro.temple.edu/~kasday/wai/tabs/bottbuttons.html The page shows buttons with textual labels. - It should work in any browser with sufficient CSS 2 support, although it doesn't rely on CSS entirely. I use tables to retain layout in older browsers. In such browsers, the text should overlay he buttons when style sheets are on, but appear above them when style sheets are off. - Works per expectation in MSIE 5+ - In Netscape 4.72 , the labels are above the buttons when style sheets are off, even in 4.72. I expect better in Mozilla but haven't tested. - Opera 3.x same as Netscape 4. Haven't tested in Opera 4.x. - Haven't tested in Amaya either. In all cases, you can click anywhere on button. Another feature is that one button always at extreme left and other two at extreme right. This was requested by the designer for a particular application. So it's always functional. It's a judgment call about serious it is that labels appear above rather than on the buttons in older browsers. Note that some pages, e.g. www.outpost.com, put labels above tabs anyway.
