  data() {
    return {

}
</script>
 
<style>
.text {
  color: v-bind(color);

const theme = {

</script>
 
<template>
  <p>hello</p>
</template>
 
<style scoped>
p {
  color: v-bind('theme.color');
}
</style>

<script setup>
import { computed } from 'vue';
const props = defineProps({ size: Number });
 
const sizePx = computed(() => `${props.size}px`)
</script>
 
<template>
  <p>hello</p>
</template>
 
<style scoped>
p {
  font-size: v-bind(sizePx);
}

<script setup>
defineProps({ size: Number });
</script>
 
<template>
  <p>hello</p>
</template>
 
<style scoped>
p {
  font-size: calc(1px * v-bind(size));
}
</style>

<template>
  <p :class="$style.red">This should be red</p>
</template>
 
<style module>
.red {
  color: red;

<template>
  <p :class="classes1.red">This should be red</p>

<style module="classes1">
.red {
  color: red;
}
</style>
 
<style module="classes2">
.red {

import { useCssModule } from 'vue';
const classes1 = useCssModule('classes1');
const classes2 = useCssModule('classes2');
