Perceivable
Information and user interface components must be presentable to users in ways they can perceive.
Can they see or hear the content?
Explore Perceivable Guidelines📖 W3C Core Standard
Accessibility starts with four simple words.
The Web Content Accessibility Guidelines (WCAG) are organized under four high-level principles that provide the foundation for Web accessibility: Perceivable, Operable, Understandable, and Robust. Whether you are a developer, designer, or content creator, these are the standards you build toward.
Operable
User interface components and navigation must be operable across all input methods.
Can they use the interface?
Master Operable ControlsUnderstandable
Information and the operation of the user interface must be understandable to everyone.
Can they make sense of it?
Apply Understandable StandardsRobust
Content must be robust enough to be interpreted reliably by a wide variety of user agents.
Will it work with their assistive tech?
Build Robust ImplementationsSimpleAccess Insight: The POUR Filter
When you're building a new feature, run it through the POUR filter. If it fails even one of these principles, it is fundamentally inaccessible. Think of WCAG not as a checklist, but as a way to ensure your digital product is truly functional for every human being.
