2. Operable

Introduction to Operable

Principle 2: Operable

User interface components and navigation must be operable.

The Principle Explained

If you follow Principle 1 guidelines, visitors will be able to perceive the content of your website. Principle 2 takes things to the next level: Once visitors can perceive the content, they must be able to act on it. In other words, the content must be operable.

There are four “operable” guidelines:

  1. Make it possible to perform all tasks with a keyboard in addition to a mouse.
  2. Give users enough time to perform tasks.
  3. Avoid information that flashes or flickers — it may trigger seizures.
  4. Make it possible for users to navigate, find content, and figure out where they are.
