<marquee> elements are deprecated and must not be used
<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.
marqueeelement 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.
People with attention deficits or cognitive disabilities could become distracted by content that scrolls. If scrolling content contains links, people with limited fine motor abilities may not be able to click on the links accurately. Users with visual impairments may not be able to see the scrolling text with enough acuity to know what the content says.

This rule requires that no
blink elements are present. Flashing text can be difficult to read and blinking objects can be difficult to activate. The associated automated check finds the presence of all

As the name suggests,
blink tags cause content to flash. Though you may like the effect, blinking text can be difficult to read, and blinking objects (links, buttons, etc.) can be difficult to activate, especially for users with imprecise or limited dexterity.
It can be very difficult for people with visual and cognitive disabilities to see and understand text that blinks. Blinking text be distracting, especially for users with cognitive disabilities. It can also be difficult for some individuals to comprehend. For these reasons, the
blink element should never be used.
