CSS and JavaScript, when used properly, have the potential to allow for accessible web experiences. However, they can also significantly harm accessibility if misused. It is important to follow some best practices to ensure that your use of CSS and JavaScript maximizes accessibility and does not detract from it.

When it comes to accessibility, HTML has immediate importance. However, CSS and JavaScript can still help or damage accessibility depending on how they are used. It is crucial to consider some best practice advice to ensure that your use of CSS and JavaScript does not ruin the accessibility of your documents.

To write accessible CSS and JavaScript code, it is essential to have a basic understanding of HTML, CSS, and JavaScript. Additionally, having a clear understanding of what accessibility is and basic computer literacy is necessary.

By following these best practices, you can ensure that even complex content is as accessible as possible:

  1. Gain familiarity with using CSS and JavaScript appropriately in your web documents to maximize accessibility and not detract from it.
  2. Consider the guidelines provided by the W3C (World Wide Web Consortium) for accessibility.
  3. Follow the accessibility guidelines outlined in the WAI-ARIA (Web Accessibility Initiative — Accessible Rich Internet Applications) basics article.
  4. Stay updated with the latest accessibility standards and best practices.

Remember, CSS and JavaScript should be used in a way that enhances accessibility and does not hinder it. By following these guidelines, you can create web experiences that are accessible to a wider audience.
