Day 8 - Four principles of Accessibility
The Web Content Accessibility Guidelines (WCAG 2.0) are organized around four user-centred principles, which form the acronym POUR:
Perceivable - Information and user interface components must be presented to users in ways they can perceive with their senses
Operable - User interface components and navigation must be designed so that users can interact with them in multiple ways.
Understandable - Information and the operation of user interface must be clear and simple.
Robust - Content must be created so that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
