Visually distracting elements cause accessibility issues for users with visual impairments.
The <marquee> and <blink> elements are deprecated and should not be used in modern web applications.
Use CSS animations if movement is necessary for your design.
If your project is extremely old, or is a narrowly used novelty for amusement, you might not be able to enable this rule.
Otherwise you should always use this rule.
There are no valid modern use cases for <marquee> or <blink> elements.
