Accessibility is often framed as a moral obligation or legal requirement. Both are true, but they miss the practical benefit: accessible websites are simply better websites. They work across more devices, handle edge cases gracefully, and are easier to maintain.
Start With Semantic HTML
Before adding ARIA roles, ensure your markup is meaningful. Use buttons for actions, links for navigation, and headings for structure. Many accessibility issues are actually HTML issues in disguise.
Focus and Keyboard Navigation
- Ensure every interactive element is reachable via keyboard.
- Never remove focus outlines without providing a visible alternative.
- Test your entire flow with only the Tab and Enter keys.
Images and Media
Every image needs an alt attribute. If an image is decorative, use empty alt so screen readers skip it. For video, captions are non-negotiable. Transcripts help not only deaf users but anyone in a sound-sensitive environment.
Forms and Validation
Label every input explicitly. Error messages should be specific and associated with the relevant field. Do not rely on color alone to indicate state.
Accessibility is not a separate task. It is a quality standard, and like all quality standards, it is cheaper to build in than to retrofit.
