Accessibility

Fundamentals

WCAG = Web Content Accessibility Guidelines WAI = Web Accessibility Initiative A11y - look at the A11y project

Web should be accessible to everyone and not all disabilities are visible - making sites more accessible results in benefits to all users

MDN is a good starting point

Some use assistive technologies e.g. screen readers

Key things to look at:

• access for screen readers
• ability to tab through app (tabindex)
• colour contrast

4 principles of accessibility (known as POUR):

• Perceivable - users must be able to perceive the information presented
• Operable - User Interface forms, controls and navigation are operable (easy to use)
• Understandable - information and the User Interface must be understandable to all
• Robust - (future-proof) users must be able to access content as technology advances and improves
