Web Accessibility: Designing for Everyone

Web accessibility means designing sites that people can use, no matter their abilities or device. It benefits users with screen readers, keyboard navigation, or slow connections, and it helps everyone by making content clearer and faster to load. When you plan for accessibility from the start, you also improve search visibility and the overall user experience.

Start with structure. Use semantic HTML: proper headings, lists, landmarks, and meaningful alt text for images. A clear page order helps assistive tech and search engines. Avoid relying on color alone to convey information; provide text labels and logical contrasts.

Make interactive parts work with a keyboard. All menus, forms, and dialogs should be reachable by Tab, and focus indicators must be visible. This makes the site usable for those who cannot or choose not to use a mouse.

Media should be accessible. Provide captions or transcripts for video and audio content. If needed, include audio descriptions. When you describe visuals in text, you help all readers understand the content.

Forms and inputs must be easy to use. Attach labels to inputs, describe errors clearly, and use accessible controls. Use native HTML controls first, and only add ARIA when necessary.

ARIA and other accessibility techniques can help, but prefer native HTML first. Use ARIA only to fill gaps that HTML cannot cover, and test how it behaves with assistive technology.

Testing matters. Use a screen reader, test keyboard navigation, and check color contrast with a tool. If possible, get feedback from users with disabilities. Even small improvements add up.

Example: a contact form with labeled fields, helpful error messages, and a clearly visible submit button. A video page includes captions and a transcript, and every image has alt text.

By designing for accessibility, you reach more people and often improve performance, reliability, and search results for everyone.
