SYNTHWAVE · StealthWorm

HTML, CSS or Tailwind, and a little JavaScript. One button or a group of up to six.

By StealthWorm

Remix button

Button submission checks

Checks will appear after the preview updates.

Buttons only: no full pages, forms, cards or navigation. Put scripts in the JavaScript tab. Tailwind uses utilities from HTML and JavaScript; use complete class names. Custom CSS supports plain CSS, without @apply, imports or plugins.

Accessibility quick check

Waiting for the rendered preview…

Try Tab, Enter and Space in the preview. Check the focus ring, hover and disabled states, then enable Reduce motion. These checks are guidance, not an accessibility certification.
