Web accessibility is crucial for ensuring that everyone, including individuals with disabilities, can access and use the web. Here are some best practices to consider:
1. Use Semantic HTML
Semantic HTML elements provide meaning to the content and help screen readers and other assistive technologies to navigate and interpret the web page.
- Use
<header>
,<nav>
,<main>
,<footer>
,<article>
, and<section>
to define the structure of your page. - Use
<label>
for form controls and<alt>
text for images.
2. Ensure Keyboard Navigation
Make sure that all interactive elements are accessible via keyboard only.
- Use
tabindex
to manage the order of focusable elements. - Ensure that all form controls have associated
<label>
elements.
3. Provide Text Alternatives
Offer text alternatives for non-text content so that it can be read by screen readers and other assistive technologies.
- Use
<img alt="description">
for images. - Provide captions for videos and transcripts for audio content.
4. Use High Contrast Colors
Ensure that there is sufficient contrast between text and background colors for users with visual impairments.
- Use tools like the WebAIM Contrast Checker to test color contrast.
- Avoid using color as the only means of conveying information.
5. Make Forms Accessible
Forms should be easy to navigate and understand for all users.
- Use
<fieldset>
and<legend>
to group related form elements. - Clearly label form controls and provide instructions where necessary.
6. Use ARIA (Accessible Rich Internet Applications) Landmarks
ARIA landmarks help to define the roles and states of web elements for assistive technologies.
- Use
role="button"
for clickable elements that are not native buttons. - Use
aria-expanded
,aria-hidden
, andaria-live
to provide additional information about dynamic content.
7. Test for Accessibility
Regularly test your website for accessibility issues.
- Use tools like axe, Lighthouse, and WAVE to identify and fix accessibility issues.
- Consider manual testing with users who have disabilities.
