• Validate your pages using the HTML Validator add-on for Firefox. Fix all errors and warnings before turning in.
  • Post-rendered HTML Validation:
    • In Firefox, view the page source or double click the icon at the bottom / in the status bar
    • Always fix the error on top first.
    • Only fix one or two errors at a time. Many times, fixing the top error fixes errors below it.
    • Process: fix one error; close page source; refresh page; re-open page source; repeat
       
• Check accessibility issues using the Accessibility Extension add-on for Firefox. Fix failures before turning in.
  • Accessibility > Reports > Accessibility Issues
  • Validate against FAE rule set
  • This will not fix all accessibility issues, but it is a very good start.
