Tim, As far colors go, I really don't think they should even be an issue. If you have experimented or developed to XHTML then the concept of color within your actual HTML document does not (should not?) exist, it must all be done via your CSS. Thus, with CSS removed the end result *should* be essentially black text on white (gray?) background, although this is generally up to the user agent/software owner. Some tools such as lynx will output black on grey, in the major contender browsers I believe the default colors re black and white, although they allow the owner to specify other combinations if they so choose. But if the style sheet support is removed, then color as defined by the content author is nullified. The Web Design Group (www.htmlhelp.com) offers a couple of little tools they call WiDGets which extend right-click functionality to IE 5+. One of the tools they offer disables style sheets; it's a tool I use all the time. (Note, it only disables linked or @import style sheets... in-line styles are not affected) JF > > All- > > I wanted to get your opinions on what it really means for a page to be > readable when style sheets are disabled.
