Compare Split Image

Before-and-after frame split by a draggable-looking divider that travels right on hover, wiping the flat ungraded shot away to expose the colour-graded version underneath.

What do I do with this?

  1. Put compare-split-image-15713.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-v14-av-compare-15712">. 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 compare-split-image-15713

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 left (and clip-path). 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 left 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
