Split Flap Board in HTML/CSS/JS.
A mechanical split-flap board, the kind that hangs in stations. Click it and every tile riffles through its flaps to the next result, rows cascading left to right, each tile landing on its own beat like a real drum.
Drop Split Flap Board into any HTML page
Split Flap Board 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.

Common questions
- Does Split Flap Board 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 Split Flap Board 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.
Copy the HTML/CSS/JS code
The full HTML/CSS/JS implementation lives on the component page, with the live demo, every format side by side, and the ability to edit and re-run it in the browser.
