What is an accessible website?

In short, an accessible website is inclusive to all users, regardless of  web browsing experience or any physical disabilities they may have.

The Web Content Accessibility Guidelines (WCAG) explain how to make web content accessible to people with disabilities.

Perceivable: Information and user interface component must be presentable to users in ways they can perceive.

  • Provide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, speech, or simpler language.
  • Provide alternatives for time-based media.
  • Create content that can be presented in different ways (for example simpler layout) without losing information or structure.
  • Make it easier for users to see and hear content including separating foreground from background.

Operable: User interface components and navigation must be operable.

  • Make all functionality available from a keyboard.
  • Provide users enough time to read and use content.
  • Do not design content in a way that is known to cause seizures.
  • Provide ways to help users navigate, find content, and determine where they are.

Understandable: Information and the operation of the user interface must be understandable.

  • Make text content readable and understandable.
  • Make Web pages appear and operate in predictable ways.
  • Help users avoid and correct mistakes.

Robust: Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.

  • Maximize compatibility with current and future user agents, including assistive technologies.

In cases where you can’t make the website or web content accessible, information it contains must be made available upon request.
