How to use it

Paste the HTML where the animation should appear.
Add the CSS to your stylesheet. PasteMotion has already scoped any global rules to the element.
Adjust the custom properties (--accent, --color-2, --color-3, --speed) on .button to restyle it without touching the rest.
Reduced-motion users are covered: the animation calms down or stops when that setting is on.
