Preparation HTML

<script type="module">
import { css } from "https://unpkg.com/@microsoft/fast-element@2.0.0/dist/fast-element.min.js"

globalThis.css = css;

const CustomStatesSetSupported = CSS.supports('selector(:state(g))');

const statesMap = new Map();

globalThis.stateSelector = function stateSelector(state) {
  return (statesMap.get(state) ??
    statesMap
      .set(state, CustomStatesSetSupported ? `:state(${state})` : `[state--${state}]`)
      .get(state));
}
</script>

Setup

const fooState = stateSelector('foo');
const barState = stateSelector('bar');
const bazState = stateSelector('baz');

const fooPartial = css.partial`:is(:state(foo), [state--foo])`;
const barPartial = css.partial`:is(:state(bar), [state--bar])`;
const bazPartial = css.partial`:is(:state(baz), [state--baz])`;
