Learn practical accessible web design techniques covering alt text, contrast, keyboard navigation, forms, headings, media and assistive technology.
Accessibility means designing websites so people with different abilities can perceive, navigate and use digital content. It is not a final checklist added after design; it should influence content, structure, interaction and development from the beginning.
Provide meaningful alternative text for informative images, captions or transcripts for relevant media and sufficient contrast between text and its background. Decorative images should not create unnecessary noise for assistive technology.
Users should be able to navigate important parts of the website with a keyboard. Focus states should be visible and interactive components should not require a single input method.
Use clear headings, predictable navigation, descriptive labels and understandable error messages. Forms should explain what information is required and why.
Web content should work with current assistive technologies and common browsers. Use semantic HTML or platform components where possible instead of building every interaction from scratch.
Label every field clearly, associate error messages with the correct field and make it possible to review or correct information before submission where appropriate.
Write alt text based on the purpose of the image. Provide captions for spoken video content and transcripts where useful. Do not put essential text only inside images.
Do not rely on color alone to communicate meaning. Use readable font sizes, adequate spacing and sufficient contrast.
Automated accessibility tools can find certain issues, but manual keyboard testing and assistive-technology testing are also important. Where possible, include people with disabilities in usability testing.
Legal obligations differ by country, sector and service. WCAG is a technical accessibility standard, but a website's legal requirements depend on the applicable jurisdiction and business.
The Web Content Accessibility Guidelines are internationally recognized guidelines for making web content more accessible.
