Website accessibility helps more people perceive, understand, navigate, and use your content. It should be included in design, writing, development, and testing.
Use a logical heading structure
Give each page a clear main heading and organize sections with meaningful subheadings. Do not choose heading levels only for their visual size.
Support keyboard navigation
Menus, links, buttons, forms, dialogs, and other controls should work without a mouse. Focus needs to be visible and move through the page in a sensible order.
Check text and interface contrast
Text, icons, borders, and focus indicators need enough contrast against their backgrounds. Test the real combinations used in default, hover, focus, error, and disabled states.
Write useful alternative text
Describe the purpose of an informative image in context. Decorative images can use empty alternative text so they do not add noise. Avoid repeating nearby captions unnecessarily.
Label forms clearly
Every input should have a persistent label. Explain required formats and place helpful error messages near the field that needs correction.
Make links and buttons understandable
Use labels that describe the destination or action. Avoid repeated vague text such as “click here,” especially when several links appear together.
Provide media alternatives
Videos may need captions, and audio information may need a transcript. Do not rely on sound alone to communicate an alert or instruction.
Respect zoom, reflow, and motion preferences
Content should remain usable when text is enlarged or the viewport is narrow. Avoid essential interactions that depend on animation and support reduced-motion preferences.
Combine tools with human testing
Automated checks can find some issues, but they cannot confirm whether content is understandable or a task is easy to complete. Include keyboard checks and testing with assistive technology in regular reviews.
Accessibility overlaps with good website user experience, clear navigation, and a readable color system.
