前端页面左右布局，点击左div增加动画过渡效果

效果图如下

以下代码基于Vue2

<template>
  <div class="container">
    <div class="left-section" :style="{ width: widthLeft + 'vw' }" @click="toggleRightSection"></div>
    <div class="right-section" :style="{ width: (100 - widthLeft) + 'vw' }"></div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      widthLeft: 60  // 左侧初始宽度
    };
  },
  methods: {
    toggleRightSection() {
      // 切换宽度
      if (this.widthLeft === 60) {
        this.widthLeft = 100;  // 隐藏右侧盒子
      } else {
        this.widthLeft = 60;  // 显示右侧盒子
      }
    }
  }
};
</script>

<style>
.container {
  display: flex;
  height: 80vh;
  overflow: hidden;
}

.left-section {
  transition: width 0.3s ease-in-out;
  background-color: #e0e0e0;
  padding: 20px;
}

.right-section {
  transition: width 0.3s ease-in-out;
  background-color: #c0c0c0;
  /* padding: 20px; */
}
</style>
