A plain-language explanation
WCAG are international guidelines for the accessibility of web content for people with different needs and ways of using technology.
Where it helps in practice
The guidelines structure digital accessibility so people with varied needs can use content and interfaces.
The decision before implementation
Set the target level, include accessibility in design and code and do not rely on an automated scanner alone.
How to verify the result
Combine tools with keyboard, screen reader, zoom and user-task testing and assign remediation owners.
