WCAG (the Web Content Accessibility Guidelines)
4 Principles(POUR) of WCAG
1. Perceivable
This helps us keep in mind that just because something is perceivable with one sense such as sight, that doesn't mean that all users can perceive it.
2. Operable
Operable can users use UI components and navigate the content. eg stg which requires a hover interaction cannot be operated by someone who can't use a mouse or is using a touchscreen.
3. Understandable
Can users understand the content? Also, can all users understand the interface and is it consistent enough to avoid confusion?
4. Robust
Is it robust enough for the content to be consumed by a wide variety of user agents? And does it work with assistive technology?
