Rule Description

<marquee> elements must not be present because they are deprecated, increase difficulty for users with limited dexterity, and are distracting for users with cognitive or attention deficits.

The Algorithm, in Simple Terms

Ensures that the deprecated <marquee> element is not used

Why this is Important

The <marquee> element creates scrolling text that is difficult to read and click on. Beyond that, it can be distracting to viewers, especially to those with low vision, cognitive disabilities, or attention deficits.

How to Fix the Problem

Deprecated elements which are presentational in nature have typically been replaced by cascading style sheets (CSS), and their use may interfere with the ability of assistive technologies to properly render content.

Remove all <marquee> elements, even if they are empty.
