Web accessibility principles

Your site must present information in ways people can recognise and understand.

Operable

Navigating and interacting

Users must be able to access your content by mouse, voice, touch or keyboard.

Understandable

Knowing what to do and what comes next

Your site must be easy for people to use and understand.

Robust

Browser and devices interpreting HTML

Your site must work with different web browsers and assistive technologies.
