Description
The rule determines if the element has a defined background-image and raises a warning. Background images that convey information or meaning must have an accessible alternative.
Context
Background images aren’t available to assistive technologies such as screen readers and aren’t supported on devices with minimal support for CSS. Additionally, a background image may not load.
How to fix it
Ensure that the background image does not convey important information that is otherwise unavailable.
This rule requires manual verification.
