How it works

Pure CSS effect — no JavaScript dependency.

Make it yours

You can tweak:

• the colors, size and timing straight in the CSS

Add it in 3 steps

1. Paste the HTML where you want the effect on your page.
2. Add the CSS to your stylesheet (or in a <style> tag).
3. Tweak the colors and CSS variables to match your brand — nothing to install.

Browser support

Works in every modern browser (Chrome, Firefox, Safari, Edge). Responsive, with graceful degradation.
