Loaders animation · .sds-loader-spin-fade

Spin Fade

Four horizontal bars fade in rotational sequence like a spinner. Add the class .sds-loader-spin-fade 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-spin-fade"><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 opacity — compositor-only, so it never causes page reflow. 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-spin-fade"><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-spin-fade"><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-spin-fade"><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.
