Spring’15 Class notes: Class 22 – Web accessibility, Interface controls

2 Apr

We began class with guests who talked about the importance of Web accessibility and provided some tips for making websites accessible to people with disabilities:

  • don’t rely on color alone to communicate meaning
  • test your color scheme for contrast
  • write meaningful alt text for images
  • use structural elements for headings, lists, etc.
  • do not turn off keyboard navigation
  • use large click targets
  • write meaningful link text

I cannot share their slides publicly, but you can find them on the CN under the daily plan for Class 22.

We then brought together various interface languages by understanding the underlying grammar of interface controls. The slides I showed in class are below.


  • remember the types and controls and their definitions
  • follow accepted patterns (speak the language you choose correctly)
