Guidelines for Accessible Web Design / Maintenance

 It is essential to ensure that your websites are accessible in order to provide equal access and equal opportunity to all staff and students.

When designing / maintaining websites ensure you:

Designing your site:internet logo

  • Consider accessibility from the very beginning,
  • Use consistent navigation.
  • Use a range of media on your webpages. The use of multimedia can produce an accessible browsing experience for users with a variety of disabilities and a variety of preferred learning styles.
  • Where multimedia is used, ensure information is available for those who cannot access that medium. For example, you can have alt text on images, or you can have a textual or sound file alternative describing an animation.
  • Seek feedback from users regarding accessibility.

 

Accessibility Testing:

Do some or all of the following:

  • Ask potential user who may experience problems to check your site for accessibility (e.g. visually impaired, colour blind or dyslexic users).
  • View your site through a text reader,
  • View your site with a screen reader,
  • View the site under different conditions (e.g. using different web browsers),
  • Run an automatic accessibility validation tool,
  • Commission an accessibility audit.
