Some helpful CSS snippets written in Houdini.

How to use

  2. Load the paint worklet CSS.paintWorklet.addModule('paintworklet.js').
  3. Use them in CSS!

1. Tooltip: (preview)


Tip: You can inspect the preview page to see them in action and play around with them.


<span>This is a tip</span>
  span {
    background-image: paint(tooltip);  /* Apply the tooltip paint rule */
    /* ... Optional: customize variables (see below) and other normal CSS for positioning, etc. */

<!-- Import the CSS Houdini -->
