Inputs animation · .sds-input-border-beam

Border Beam

Border Beam — input animation. Add the class .sds-input-border-beam to any element — it loops continuously as soon as the class is applied, with no JavaScript.

Live demo

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/inputs.min.css" />

<input class="sds-input-border-beam" placeholder="Type here" />

Loads only the inputs 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 as soon as the class is applied, looping continuously. It animates an expanding outline. Timing is fixed for this effect, but you can still override animation-duration/timing-function on the element.
