Web Content Accessibility Guidelines ()
Established after the second International Conference on the World Wide Web in 1995. At first, these guidelines were just shots in the dark, but today we know that the most accessible and user-friendly websites have four main principles: they are perceivable, operable, understandable, and robust.
- Perceivable: This means people should be able to see and read your website, even if their vision is impaired.
- Operable: If you can only access your site from one type of device, it isn’t user-friendly. Websites should be responsive and easy to navigate across multiple browsers and mobile devices.
- Understandable: Websites should be organized and use language that most customers understand.
- Robust: Sites should integrate with plugins or that web users with disabilities might rely on, and have future ability to do so as well.
