The Four Principles of Web Accessibility

Perceivable

Information and user interface components must be presentable to users in ways they can perceive.

Operable

User interface components and navigation must be operable.

Understandable

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

Robust

Content must be robust enough to work reliably with current and future user tools.

The Web Content Accessibility Guidelines (WCAG) 2.1 provides a wide range of recommendations for making web content more accessible. It focuses on four principles:

  • Perceivable
  • Operable
  • Understandable
  • Robust

Each principle has success criteria at three levels of accessibility: A (minimum), AA (mid-level), and AAA (high level). Implementing at least AA to meet legal requirements in most countries.
