Rule aeo-2ba100c878e76e9d · content_validator · hypothesis, not yet confirmed

Label every button, icon, and form field with a descriptive accessible name in the HTML; fix unlabelled icon buttons in global headers first.

Applies to: all

Hypothesis: the reasoning is published, but no independent evidence confirms it yet. Test it on your own pages before you rely on it.

Why this matters

AI agents rely on the accessibility tree, and unnamed controls may be unusable to them; one fix in a global header applies across every page.

Type: validator

Icon-only buttons with no aria-label or accessible name.
