vue3中css里的v-bind

<template>
    <div class="ruben">
        <p>You clicked {{ count }} times</p>
        <button @click="increment">Click me</button>
    </div>
</template>

<script>
export default {
    data() {
        return {
            count: 1
        }
    },
    methods: {
        increment() {
            this.count++
        }
    }
}
</script>

<style scoped>
.ruben {
    transform: scale(v-bind(count));
}
</style>
