Will It Vibe?Deprecated <marquee> element used
Part of Documentation, UX & Accessibility, which counts for 15% of the overall score. When this check fires it deducts 4 points from that category, once per scan, no matter how many places it turns up.
What it detects
<marquee> renders auto-scrolling text that cannot be paused by the user, is a known trigger for vestibular and attention disorders, was removed from the HTML5 standard, and has inconsistent or absent screen-reader support. Replace it with a static message, or with a CSS/JS carousel that has explicit pause/stop controls and respects prefers-reduced-motion.
Why it matters
<marquee> was removed from the HTML5 standard, cannot be paused or stopped by the user, and is a documented trigger for attention and vestibular issues in users sensitive to constant motion. Screen-reader support for it is inconsistent at best, so the same element that is disorienting for sighted users is also often just skipped or mangled for assistive technology.
How to fix it
Replace it with static text if the scrolling added no real information, or with a proper carousel/ticker component that has visible pause/stop controls and respects prefers-reduced-motion by defaulting to paused or static for those users.
