代码

<template>
  <div class="container">
    <!-- 左侧区域 -->
    <div class="left-side" :style="{ width: leftWidth + 'px' }">
      左侧内容
    </div>
    
    <!-- 右侧区域 -->
    <div class="right-side" :style="{ left: leftWidth + 'px' }">
      <div class="content">
        <button @click="toggleLeftWidth">切换左侧宽度</button>
        <p>右侧内容区域，占据剩余空间</p>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      leftWidth: 200, // 初始宽度200px
      isCollapsed: false
    }
  },
  methods: {
    toggleLeftWidth() {
      this.isCollapsed = !this.isCollapsed;
      this.leftWidth = this.isCollapsed ? 64 : 200;
    }
  }
}
</script>

<style lang="less" scoped>
.container {
  position: relative;
  width: 100%;
  height: 100vh;
  overflow: hidden;
  .left-side {
    position: fixed;
    left: 0;
    top: 0;
    height: 100%;
    background-color: blue;
    transition: width 0.3s ease;
    padding: 20px;
    box-sizing: border-box;
  }

  .right-side {
    position: fixed;
    top: 0;
    right: 0;
    bottom: 0;
    background-color: red;
    transition: left 0.3s ease;
    padding: 20px;
    box-sizing: border-box;
