Why it matters#

The obsolete <blink> and <marquee> elements move or flash content automatically with no way to pause, stop, or hide it. This distracts (and can harm) many users, and the motion cannot be controlled.

How to fix#

Remove <blink>/<marquee>. If movement is genuinely needed, build it so it can be paused/stopped and respects prefers-reduced-motion.

Example#

<marquee>Breaking news</marquee>

<p>Breaking news</p>
