WCAG 2.1·Perceivable·1.1 Text Alternatives

1.1.1 Non-text Content

Level A

Every non-text element (images, icons, charts, audio) needs a text alternative that conveys the same information.

Why it matters

Screen-reader users rely on alt text to understand images; without it, the image effectively does not exist for them.

Common failure
<img src="/logo.png">
Accessible version
<img src="/logo.png" alt="Acme Co. logo">

How OnlyEnable handles this

Partially mitigated. OnlyEnable injects placeholder alt attributes at runtime, but only your team can write meaningful descriptions.
