In fact IE7 is one of the last browsers to do zoom - only about a decade after it started appearing in browsers. On the other hand, I only know of a couple of mobile browsers that provide zoom, and I suspect it is still an issue for now. >> b) will the sections that reccommend to use em units be modified to >> reflect new zooming techniques in browsers? > > No, using scalable fonts is still a sufficient technique to satisfy > this success criterion. > >> b) is horizontal scrolling when using zoom a no-go for accessibility or >> is it more a usability issue and a consequecne of AA classification? > > It is an accessibility issue, which is why it is included in WCAG. > However, there is some content for which it will not be possible to > scale the content in a way that doesn't require horizontal scaling > (e.g. large complex data tables). Well, using a table transformation tool it is possible to avoid it, but people don't generally do that :( On the other hand using something like fit-to-width in combination with zoom wil deal with some of the issue - by breaking anything that you used to try and force your site to maintain a particular layout. Adaptive layout is still an important technique for users, so building a layout that can handle being adapted is a pretty good idea. cheers chaals -- Charles McCathieNevile, Opera Software: Standards Group hablo español - je parle français - jeg lærer norsk chaals@opera.com Catch up: Speed Dial http://opera.com
