Dithering for HTML/CSS/JS - GSAP component

Annnimate

Every component, in every framework.

Dithering is one of 50+ GSAP components, each shipping in React, Vue, and HTML/CSS/JS with the same production tuning.

Drop Dithering into any HTML page

Dithering ships as plain HTML, CSS, and JavaScript - no build step, no bundler, no framework. Copy the three blocks (HTML markup, CSS styles, JS init) and paste them into any page. The component works in any CMS that lets you embed custom code: Webflow, Framer, Astro, vanilla HTML, WordPress, Squarespace.

Where it goes in your page

Paste the HTML markup wherever the component should appear. Add the CSS to your stylesheet (or in a <style> tag). Add the JavaScript inside a <script> tag at the end of <body>, or in your site's footer custom code block.

In Webflow specifically: HTML goes in an Embed block, CSS goes in the page or project Custom Code <head> section, JS goes in the page Custom Code <body> section. The JSON paste flow (Designer → paste) handles the structure + classes for you; the Custom Code drop-ins handle the script and any custom CSS the JSON can't carry.

The component initializes on DOMContentLoaded automatically - no manual call needed.

HTML / vanilla-JS gotchas

Load GSAP BEFORE the component script

The component script calls gsap.to() at init. If GSAP isn't loaded yet, you'll see ReferenceError: gsap is not defined. The included waitForGSAP helper handles this gracefully, but easier: just include the GSAP CDN <script> above the component script.

Plugins need separate CDN scripts

Core GSAP is one script. ScrollTrigger, SplitText, Flip, and other plugins each need their own <script> tag from the GSAP CDN, loaded after the core. Check the component's dependency list to know which to include.

Multiple instances on one page

The component is wrapped in an IIFE and selects by data-anm-* attributes, so multiple instances on the same page work without conflict. Each is initialized independently. To target a specific instance from your own code, use window.Anm.{ComponentName} APIs documented in the Tips section.

Common questions

Does Dithering work in Webflow?

Yes. The component ships with both a Webflow-compatible JSON paste (for the Designer) and standard HTML/CSS/JS for projects that prefer Custom Code. The Webflow tab on the main detail page has both formats.

Does Dithering work in WordPress, Squarespace, Framer, Astro, or other no-code platforms?

Yes. Anywhere you can add custom HTML, CSS, and JavaScript - the component works. Paste the markup into your page, add CSS to the styles section, and add JS to the script section. No framework required.

Do I need a build step for this version?

No. The HTML version is plain, copyable code that runs directly in the browser. No bundler, no transpiler, no npm install. Just paste and it works.

Can I use this with TypeScript?

The HTML version is plain JavaScript - no TypeScript types. If you want TypeScript, the React or Vue variants ship with proper type definitions. The HTML version is intended for projects that don't have a build step.
