Accessibility is not a feature; it's a fundamental requirement. When we design for accessibility, we design for everyone.
Over 1 billion people worldwide experience some form of disability. Ignoring accessibility means ignoring a significant portion of your potential audience. Furthermore, many accessibility improvements like clear contrast and semantic HTML benefit all users.
The core principles are perceivable — information and user interface components must be presentable to users in ways they can perceive. Operable — user interface components and navigation must be operable. Understandable — information and the operation of user interface must be understandable. And robust — content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
Let's build a web that works for everyone.
