When I was a kid, my dad used to ask me 'how do you keep a turkey in suspense?', which used to annoy me a lot. I never did find out the answer... -----Original Message----- From: deborah.kaplan@suberic.net [mailto:deborah.kaplan@suberic.net] Sent: Thursday, August 14, 2014 2:35 PM To: accessys@smart.net Cc: Katherine Mancuso; Judy Okite; Bryan Garaventa; Mark Sadecki; WAI Interest Group Subject: Re: For you: A webpage that is 100% accessible to all people around the world, regardless of nationality or disability or Assistive Technology The page is basically a joke, playing on the idea that there is no such thing as a 100% accessible page; it's blank, with empty HTML source. Given how many people in the community are viewing on mobile -- or are using screen readers and are used to theoretically accessible pages that report nothing back to them -- it's worth being more explicit about why you can't access the page. :) Deborah Kaplan On Thu, 14 Aug 2014, accessys@smart.net wrote: > > apparently only if using windows > > Bob > > > On Thu, 14 Aug 2014, Katherine Mancuso wrote: > >> Date: Thu, 14 Aug 2014 14:06:06 -0700 >> From: Katherine Mancuso <kmancuso@gmail.com> >> To: Judy Okite <judyokite@gmail.com> >> Cc: Bryan Garaventa <bryan.garaventa@whatsock.com>, >> Mark Sadecki <mark@sadecki.com>, WAI Interest Group >> <w3c-wai-ig@w3.org> >> Subject: Re: For you: A webpage that is 100% accessible to all people >> around the world, regardless of nationality or disability or Assistive >> Technology >> Resent-Date: Thu, 14 Aug 2014 21:06:54 +0000 >> Resent-From: w3c-wai-ig@w3.org >> >> Functioning as expected.
