Making Web Pages Accessible

Accessible Web Pages

Accessible web pages help ensure that all users, including people who use assistive technologies, can read, understand, and navigate your content.

The Web Content Accessibility Guidelines, or WCAG, organize accessibility around four core principles:

Perceivable
Content must be presented in ways users can perceive.
Operable
Navigation and interface components must be usable with different input methods.
Understandable
Content and navigation must be clear and predictable.
Robust
Content must work with a wide range of browsers and assistive technologies.

Use the sections below to learn about key elements of accessible web pages.

Use headings to create a clear page structure. Headings should follow a logical order and help users quickly understand how content is organized.

Write descriptive link text that clearly tells users where the link goes. Avoid vague phrases such as “click here” or “learn more.”

Use tables only for tabular data, not layout. Include appropriate header rows or columns so users can understand relationships between data.

Make sure forms include properly associated labels, clear instructions, and accessible error messaging.

Interactive elements should be keyboard accessible and maintain a visible focus state so users can track where they are on the page.

Use bulleted and numbered lists when presenting grouped information. Lists improve structure and make content easier to scan.

Provide alt text for meaningful images so users who cannot see them can still understand their purpose or content.

Use sufficient color contrast and do not rely on color alone to communicate meaning.
