Content accessibility principles

Web accessibility is the ability for a person with a disability to understand and use a web site, application, intranet, or program. It allows people with disabilities to access information like anyone else; interact with others without being classed as “disabled” and allows them to undertake activities which they may not otherwise be able to do.

Website content accessibility is important to people with the following disabilities:

  • Blindness
  • Colour-blindness
  • Low vision
  • Deafness
