Identify Accessibility Standards

  • The standards or legislation defines how to make web content more accessible to people with disabilities. WACG 2.0 has 12 guideline that are organised under 4 principles which include:

    - Principle 1: Perceivable - Information and user interface components must be presentable to users in ways they can perceive.


  • Principle 2: Operable - User interface components and navigation must be operable.

  • Principle 3: Understandable - Information and the operation of user interface must be understandable.

  • Principle 4: Robust - Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.


Principle 2: Operable - User interface components and navigation must be operable.

  • Guideline 2.1 Keyboard Accessible: Make all functionality available from a keyboard.

  • Guideline 2.2 Enough Time: Provide users enough time to read and use content.

  • Guideline 2.3 Seizures: Do not design content in a way that is known to cause seizures.

  • Guideline 2.4 Navigable: Provide ways to help users navigate, find content, and determine where they are.
