It seems text-decoration-thickness is not yet animateable in chromium with transition 😭

---

I have to correct myself: CSS Houdini makes this possible ✨🧙✨:

<h1>Hello, World!</h1>

<style>
  @property --thickness {
    syntax: "<length>";
    inherits: true;
    initial-value: 0px;
  }
  h1 {
    --duration: .3s;
    --thickness: .1em;
    text-decoration: underline;
    text-decoration-color: black;
    text-decoration-thickness: var(--thickness);

    transition: --thickness var(--duration);
  }
  h1:hover {
    --thickness: .2em;
  }
</style>
