even better.

Evaluating web pages for accessibility

Easier to build an accessible site from scratch than to fix an existing site

Use testing software like Bobby or LIFT - but won’t find all accessibility errors



Turn off sound

Use a text-only browser such as Lynx or Lynx simulator

Unplug the mouse, use keyboard only



Have people with disabilities who regularly use assistive technology test the site and give feedback
