Axe Core 4.6

<marquee> elements are deprecated and must not be used

Elements of type <marquee> are prohibited because they are deprecated, add difficulty for users with limited dexterity, and distract users with cognitive or attention problems.

The marquee element produces difficult-to-read and-click-on scrolling text. Furthermore, it can be disturbing to viewers, particularly those with low eyesight, cognitive impairments, or concentration difficulties.

People with attention difficulties or cognitive impairments may be distracted by scrolling content. People with inadequate fine motor skills may not be able to precisely click on links inside scrolling content. Users with visual impairments may not be able to read the content of the scrolling text with sufficient clarity.
