  • Guideline 1.2 Provide synchronized media equivalents for time-dependent presentations.
  • Guideline 1.3 Ensure that information, functionality, and structure are separable from presentation.
  • Guideline 1.4 In visual presentations, make it easy to distinguish foreground words and images from the background.
  • Guideline 1.5 In auditory presentations, make it easy to distinguish foreground speech and sounds from background sounds. [level 2 guideline]
• Principle 2: Interface elements in the content must be operable.
  • Guideline 2.1 Make all functionality operable via a keyboard or a keyboard interface.
  • Guideline 2.2 Allow users to control time limits on their reading or interaction unless specific real-time events or rules of competition make such control impossible.
  • Guideline 2.3 Allow users to avoid content that could cause photosensitive epileptic seizures.
  • Guideline 2.4 Facilitate the ability of users to orient themselves and move within the content. [level 2 guideline]
  • Guideline 2.5 Help users avoid mistakes and make it easy to correct them. [level 2 guideline]
• Principle 3: Content and controls must be understandable.
  • Guideline 3.1 Ensure that the meaning of content can be determined.
  • Guideline 3.2 Organize content consistently from "page to page" and make interactive components behave in predictable ways.
• Principle 4: Content must be robust enough to work with current and future technologies.
  • Guideline 4.1 Use technologies according to specification.
  • Guideline 4.2 Ensure that user interfaces are accessible or provide an accessible alternative(s)
