What do I do with this?

  1. Put focus-toolbar-textarea-15399.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-in-toolbar-15398">. 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 focus-toolbar-textarea-15399

Was this useful?

Motion safety

Static estimate, read from the CSS

Reduced motion
Brief motion, no guard

Animates briefly or on interaction. Only looping motion gets a guard in this catalog; copy the one from the Insights tab if this ships on a critical path.

What it animates
Reflows

Animates max-height, padding (and background, border-color, box-shadow, 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 max-height, padding on a box in flow, so content beside or after it can move. Measured in Chromium: layout-shift score 0.0004 across 9 shifts in 7.6 s, one preview with a neighbour beside it. Not a page-level CLS.

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

38 more effects in Inputs & Hover

All of them free to read, copy and install — no account, no locked tiles, no watermarked preview. The whole catalog is open, and so are the API and the CLI.
