- Put
morphing-blob-shape-15327.cssanywhere your page already loads CSS from — in Next.js that isapp/globals.css, or any stylesheet with a<link>in your HTML. - Then put the class on the element you want it on:
<button class="fx-v12-ic-blob-15326">. 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.

Motion safety
Static estimate, read from the CSS
- Reduced motion
- Guarded
Ships a
prefers-reduced-motionblock, so the loop settles into its end state for visitors who ask for less motion. - What it animates
- Repaints
Animates
border-radius. No reflow, but the browser repaints every frame, which is fine for one element and costly across many. - 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)
- No shift expected
Nothing it animates moves or resizes the box in flow. 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
