Success Criterion 1.1.1
Conformance level A

Complex Infographic With No Long-Form Text Description

1.1.1 — Non-text Content

Scenario

Setting

An online clothing store's product listing page

What’s wrong

Complex images (charts, diagrams, infographics) with only a short alt and no long description mechanism anywhere.

Example

<img src="chart.png">

Why it matters

Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning.

How to test

Look for a 'read more', linked detail page, or expandable description near complex images (charts, infographics, diagrams): if only a one-line alt exists, it fails.

How to fix

Add a long description mechanism (adjacent text, linked page, or collapsible detail) for complex images.

<img src="chart.png" alt="Q3 revenue chart showing 12% growth">

The alt attribute gives assistive technology the same information the image conveys visually.

Outcome

On an online clothing store's product listing page, this barrier is gone for blind and low-vision people using screen readers — they reach the same outcome without extra effort.
