Web Content Accessibility Guidelines 2.0

Web Content Accessibility Guidelines 2.0 - W3C Working Draft 11 December 2007

There are four principles that provide the foundation for Web accessibility covered by these guidelines. Under the principles are 12 guidelines that should be worked toward in order to make content more accessible to users with different disabilities.

Perceivable

• 1.1 Provide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language
• 1.2 Provide synchronized alternatives for synchronized media
• 1.3 Create content that can be presented in different ways (for example simpler layout ) without losing information or structure
• 1.4 Make it easier for users to see and hear content including separating foreground from background

Operable

• 2.1 Make all functionality available from a keyboard
• 2.2 Provide users with disabilities enough time to read and use content
• 2.3 Do not design content in a way that is known to cause seizures
• 2.4 Provide ways to help users with disabilities navigate, find content and determine where they are

Understandable

• 3.1Make text content readable and understandable
• 3.2Make Web pages appear and operate in predictable ways
• 3.3Help users avoid and correct mistakes

Robust

• 4.1 Maximize compatibility with current and future user agents, including assistive technologies. The guideline includes checkpoints for meeting each guideline. Checkpoints are assigned a Priority level. The Priority levels are numbered 1, 2, and 3 and could be stated as must, should and may checkpoints.
