Example

Using in with class

without

<div class="py-3.5 grid-cols-[0.7fr_repeat(7,1fr)]">
  py-3
</div>

with

<div class="uno-0tr0xg">
  py-3
</div>

<style>
.uno-0tr0xg {
  grid-template-columns:0.7fr repeat(7,1fr);
  padding-top:0.875rem;
  padding-bottom:0.875rem;
}
</style>

Using with string

If you want to use UnoCSS rule string(const bg = 'bg-green-100/50') in <script></script> or JS/TS files, please use single quotes instead of double quotes. But if you want to ignore a string, add a prefix(default applet-ignore:), and the plugin will automatically ignore the string and delete the prefix.

without

<script setup lang="ts">
  const bg = 'bg-[hsl(2.7,81.9%,69.6%)]'
  const bg2 = 'applet-ignore: bg-[hsl(2.7,81.9%,69.6%)]'
</script>

with

<script setup lang="ts">
  const bg = 'uno-98db2v'
  const bg2 = 'bg-[hsl(2.7,81.9%,69.6%)]'
</script>

<style>
.uno-98db2v {
  --un-bg-opacity: 1;
  background-color: hsla(2.7, 81.9%, 69.6%, var(--un-bg-opacity));
}
</style>
