Vue如何利用css实现动态样式绑定

<template>
  <div :style="styleObject">
    //.....
  </div>
</template>
 
<script>
export default {
  data() {
    return {
      styleObject: {
        fontSize: '14px',
        color: '#f00'
      }
    }
  },
  methods: {
    changeStyle() {
      this.styleObject.color = '#0ff'
    }
  }
}
</script>
