Reveal Up Mask

Wipes up behind a mask. Add the class .sds-reveal-up-mask to any element — it plays once as soon as the class is applied, with no JavaScript.

Live demo

Reveal Up Mask

Demo uses this site's neutral theme; override --sds-primary to match your brand.

Quick start

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@salkomdesignstudio/sds-motion-forge/dist/categories/text.min.css" />

<h1 class="sds-reveal-up-mask">Reveal Up Mask</h1>

Loads only the text bundle (core is included).Prefer one file? Use https://cdn.jsdelivr.net/npm/@salkomdesignstudio/sds-motion-forge/dist/motion.min.css (all 604 effects).

How it works

Plays once, as soon as the class is applied. It animates a clip-path mask, opacity and movement and scale (transform) — compositor-only, so it never causes page reflow. `--sds-duration` controls the speed and `--sds-easing` controls the feel — override either on the element or :root (the sds-fast/sds-slow modifier classes do exactly that).

Typed React, Angular, Tailwind and Web Components wrappers live in packages/ in the repository and are not yet published to npm; the snippets above need only the CSS.
