Inputs animation · .sds-input-plasma

Plasma Field

Plasma glow cycles around the field. Add the class .sds-input-plasma 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-plasma" 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 its shadow/glow. `--sds-duration-dramatic` controls the speed — override either on the element or :root (the sds-fast/sds-slow modifier classes do exactly that).

Angular

//   "node_modules/@salkomdesignstudio/sds-motion-forge/dist/motion.min.css"
import { Component } from '@angular/core';

@Component({
  selector: 'app-demo',
  standalone: true,
  template: `
    <input class="sds-input-plasma" placeholder="Type here" />
  `,

export class DemoComponent {}

Tailwind CSS

/* app.css — Tailwind v4 */
@import "tailwindcss";
@import "@salkomdesignstudio/sds-motion-forge/dist/motion.min.css";

/* then use the class like any other: */
<input class="sds-input-plasma" placeholder="Type here" />

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.
