Oxford Geek Nights

Filed under: Accessibility, Talks, Web development — bryan @ 1:38 am

Two nights ago was the first Oxford Geek Night. This was basically a chance for web developers and designers to get together in a mixed business and social context.

I did one of the “microslots” - a five minute talk on “Avoiding accessibility pitfalls”. This is of course a huge area, and one I’d happily talk for hours about, so I focussed on three areas in which I keep seeing people trip up:

  1. Giving appropriate alt text
  2. Correct use of link text
  3. Using markup correctly

I’ll be elaborating on each of these areas in my next few posts; in the meantime, you can download my slides as a pdf.
