<a class="codepen-button"><span>Start Coding</span></a>

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 .codepen-button to restyle it without touching the rest.
Reduced-motion users are covered: the animation calms down or stops when that setting is on.
