Web accessibility is important for everyone, not just those with disabilities, as people use the web in many different ways and environments. Websites should be accessible to all users, including those using assistive technologies like screen readers or those with conditions like color blindness. It is important to test websites with real users with disabilities to check for accessibility issues. In addition to legal requirements, making sites accessible opens them up to more users and has other benefits like increased sales, faster site speeds, and better search engine optimization.
