Loaders animation · .sds-loader-matrix

Matrix Bars

Matrix Bars — loader animation. Add the class .sds-loader-matrix 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/loaders.min.css" />

<span class="sds-loader-matrix"><span></span><span></span><span></span><span></span><span></span></span>

Loads only the loaders 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 height and opacity. Timing is fixed for this effect, but you can still override animation-duration/timing-function on the element. The animation runs on the element's direct children — it needs child elements to be visible.

React / Next.js

import "@salkomdesignstudio/sds-motion-forge/dist/motion.min.css";

export default function Demo() {
  return (
    <span className="sds-loader-matrix"><span></span><span></span><span></span><span></span><span></span></span>
  );
}

Angular

// angular.json → architect.build.options.styles:
//   "node_modules/@salkomdesignstudio/sds-motion-forge/dist/motion.min.css"
import { Component } from '@angular/core';

@Component({
  selector: 'app-demo',
  standalone: true,
  template: `
    <span class="sds-loader-matrix"><span></span><span></span><span></span><span></span><span></span></span>
  `,
})
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: */
<span class="sds-loader-matrix"><span></span><span></span><span></span><span></span><span></span></span>

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.
