release: v3.0.0-alpha-3060420220922001

编译成小程序,但确实看到编译成了css3变量

复现过程如下

// script 中
const picwidth = ref('100px')

// style 中
.pic{
  width: v-bind(picwidth)
}

贴个方法,找了好久没找到试出来了,希望可以帮助到你。
css 的 background: src(xxx) 使用变量,在 js 中拼接好 url

<script setup lang="ts">
const imgUrl = ref(
  'url(https://p3-passport.byteimg.com/img/mosaic-legacy/3795/3047680722~180x180.awebp)'
)
</script>

<style lang="less" scoped>
.compass {
  background: v-bind(imgUrl);
}
</style>
