What makes a website accessible?
The guidelines for accessibility are organised around four key principles, which lay the foundation for accessing content on the web.
For everybody to use the web without limitation, they must be able to access content that is:
• Perceivable – Information and user interface components must be presentable to users in ways they can perceive
• Operable – User interface components and navigation must be operable
• Understandable – Information and the operation of the user interface must be understandable
• Robust – Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies
If a website fails to meet one or more of these principles, users with disabilities will experience difficulty using it. In the UK, 1 in 5 people have a disability – this could be visual, hearing, motor or cognitive.
