Perceivable
Content must be presentable in ways all users can perceive. This covers text alternatives for images, captions for video, sufficient color contrast, and content that adapts to different presentations.
Accessibility criteria, explained for everyone.
WCAG 2.2 defines 87 success criteria that make digital products accessible. But the official text is written for technical specialists. This platform translates each criterion into plain language — so anyone in your team can understand what it means, why it matters, and how to test it.
Whether you work in design, development, support, sales, or management — if your product needs to be accessible, these cards are for you.

The four principles
Every WCAG criterion belongs to one of these principles.
Operable
Users must be able to operate the interface. This covers keyboard access, enough time to interact, avoiding seizure-triggering content, and ways to navigate and find what you need.
Understandable
Content and interface must be understandable. This covers readable text, predictable behavior, and helping users avoid and correct mistakes in forms and inputs.
Robust
Content must work reliably with current and future technologies, including assistive technologies like screen readers and voice control.
