Best Practices for accessible Content

Posted by Michael Gaigg

People rarely read Web pages, they scan the page! As a result, Web pages have to follow Design Guidelines for Content that enable them to quickly identify headings, titles, links and other important elements to orient themselves. What else has to be done to be Section 508 compliant?

Basic Rules

  • Don’t rely on color alone
  • Identify the language used throughout the document and identify changes
  • Use correct markup to emphasize important content
  • Be clear and precise in the choice of wording and language
