What do I do with this?

  1. Put scrub-preview-thumbnail-15571.css anywhere your page already loads CSS from — in Next.js that is app/globals.css, or any stylesheet with a <link> in your HTML.
  2. Then put the class on the element you want it on: <button class="fx-v13-mi-scrub-15570">. The CSS does nothing until a class name in it matches something on the page.
  • Link the stylesheet, then paste the markup wherever you need it.
npx hoverlab add scrub-preview-thumbnail-15571

Was this useful?

Motion safety

Static estimate, read from the CSS

Reduced motion
Guarded

Ships a prefers-reduced-motion block, so the loop settles into its end state for visitors who ask for less motion.

What it animates
Reflows

Animates width (and background-position, color). The browser re-lays-out the page on every frame; prefer transform if you can.

Flashing (WCAG 2.3.1)
No flashing found

No repeating change in opacity, colour or brightness large enough to count as a flash.

Layout shift (CLS)
May shift layout

Animates width on a box in flow, so content beside or after it can move. A category from the CSS, not a measurement for this effect.

Every row is read from the shipped CSS. Only a figure marked measured came from a browser. Customizing the speed changes the timing, so recheck a customized copy. How it is computed
