Error Shown Only Through a Placeholder or Color Change

3.3.1 — Error Identification

Scenario

Setting

A fashion e-commerce site's checkout page

What’s wrong

Errors described only via placeholder change or color change of label.

Example

A QA pass on a fashion e-commerce site's checkout page turns this up: errors described only via placeholder change or color change of label.

Why it matters

Everyone submitting forms — especially screen-reader and color-blind users who miss color-only cues. On a fashion e-commerce site's checkout page, that means they lose their progress and have to start over.

How to test

Submit invalid data with a screen reader: if the error is conveyed only by a placeholder change or the label's color, with no separate error text, it fails.

How to fix

A text error message must identify each field in error and be exposed to assistive technology (announced automatically or focused).

Outcome

With the fix in place on a fashion e-commerce site's checkout page, they complete the form without guessing.

Who is affected

Everyone submitting forms — especially screen-reader and color-blind users who miss color-only cues.
