CSS Variable Style

To be compatible with vanilla CSS, you can use CSS custom properties to replace the @apply directive.

.custom-div {

To use rules with :, you will need to quote the value

.custom-div {
  --at-apply: "hover:text-red";
}

transformerDirectives({
  // the defaults
  applyVariable: ['--at-apply', '--uno-apply', '--uno'],
  // or disable with:
  // applyVariable: false
})
