This is true. There are people who are designing for "minor" browsers, too. Netiher strategy is a guarantee of accessibility, and in many cases sites are made inaccessible for no good reason, just a poor understanding of how the web works. I have used http://www.microsoft.com and had a different site presented to me when using IE 5 on windows from what I got using other browsers. (I just checked using IE 5 ona a Mac and iCab, and in both cases got what I think is the alternative version - no fly-out menus. I am going from memory here though - or perhaps they have changed the site). To get to the same content using the alternative cversion was possible, but involved slightly different navigation paths. This is just unhelpful design - it poses some accessibility problems particularly because it doesn't provide a predictable browsing experience for people used to using more than one browser. Using http://www.mbta.com with a browser which was capable of doing what was apparently required it was still impossible to get to certain types of content (for example an image of a map - even lynx can handle that!). On the other hand a browser which clearly did not have the capabilities required was given access. I am pretty sure that this is a piece of badly-designed browser-sniffing at work. The result is a total breakdown in accessibility. If the site works differently in different browsers that may be due to poor coding, either of the site or of a lot of browsers. But to block access deliberately is not "a corporate policy that we should take into account", it is a corporate policy to block access. (Or it may just be an oversight. Either way, it is, in my opinion, terrible design and not accessible.) cheers Charles McCN On Sun, 7 Jan 2001, Robert Neff wrote: charles, i was inferring that there are major corporations that are specifying or designed for this speciofic browser and version and this is normally netscape and IE. ----- Original Message ----- From: "Charles McCathieNevile" <charles@w3.org> To: "Robert Neff" <robneff@home.com> Cc: "Jason White" <jasonw@ariel.ucs.unimelb.EDU.AU>; "Web Content Accessibility Guidelines" <w3c-wai-gl@w3.org> Sent: Sunday, January 07, 2001 10:40 PM Subject: SSL Re: Proposal for Guideline 2 as well as a proposal to trim WCAG 2.0 to 3 guidelines (won't william be glad?) > I don't think that it is OK to say "you have to have IE or netscape to use > SSL".
