how to bind css to vue code example

Example 1: vue toggle class

<template>
  	<div>
      <div
        class="staticClass"
        v-bind:class="{ active: isActive, 'text-danger': hasError }"
      ></div>
      <!-- OR -->
      <div
           v-bind:class="[isActive ? activeClass : '', errorClass]"
      ></div>
	</div>
</template>

<script>
  export default {
  	data() {
      isActive: true,
      hasError: false,
      activeClass: 'active',
      errorClass: 'text-danger',
    }
  }
</script>

Example 2: vue conditional class

<div :class="{ 'prop-name': boolVar }"></div>

Example 3: vuejs :class

<div
  class="static"
  v-bind:class="{ active: isActive, 'text-danger': hasError }"
></div>
