I could see using an offscreen solution (e.g., that would be in the tab navigation order) so that before hitting the barrage of expandable headings, one would be given fair warning. _ Ian > > Jon > > > ---- Original message ---- >> Date: Thu, 24 Sep 2009 15:06:50 -0500 >> From: Ian Jacobs <ij@w3.org> >> Subject: Seeking input on making a feature of draft W3C site more >> accessible >> To: w3c-wai-ig@w3.org >> >> Dear WAI IG, >> >> I would like your input on a comment about the draft W3C Web site and >> would like your input on how to make a particular feature more >> accessible. >> >> The draft site includes an expand/collapse content feature.
