What is Web Accessibility?
Web accessibility is a set of rules, behaviors, code standards, and design guidelines that are used to enable people with disabilities, which comprise 20% of the world’s population, to use websites effectively.
To achieve this, the W3C (The World Wide Web Consortium) has created the Web Content Accessibility Guidelines 2.1 (WCAG 2.1), which explain about and guide developers on how to make websites accessible. These guidelines have been adopted by governments around the world and are now a part of various legislations, such as the ADA, Section 508, EN 301549, and others.
The WCAG focuses mainly on three areas of accessibility: blind people using screen-readers (JAWS, NVDA), people with motor impairments who use only keyboards, and a variety of other disabilities such as color blindness, epilepsy, and minor visual impairments that are mainly focused on the UI and design of the website (color contrasts, animations, fonts, etc.).
