Web accessibility

Accessibility is sometimes abbreviated to a11y (starts with A, ends with Y and 11 letters long).

Some level of website accessibility may be a legal or contractual requirement. Regardless of this, it is right to consider which accessibility techniques we can use to benefit our visitors.


W3C tips for web design emphasises the need for accessibility to start with the design. The W3C also publishes Easy Checks — A First Review of Web Accessibility that provides preliminary checks for any web page and a list of accessibility tools. There are then plenty of more specific resources.
