    运行效果

    方法一

    父容器div使用 position: relative;,子div使用 position:absolute;定位,注意边距问题

    html

    <div class="div-container">
      <div class="div1">1</div>
      <div class="div2">2</div>
    </div>
    

    css

    /* 方法一 */
    .div-container {
      margin: 10px 0;
      padding: 10px;
      width: 400px;
      border: 2px solid #ccc;
      position: relative;
    }
    .div1 {
      width: 100px;
      height: 50px;
      border: 2px solid red;
    }
    .div2 {
      width: 100px;
      height: 50px;
      border: 2px solid red;
      position: absolute;
      /* 边距设置 */
      right: 10px;
      top: 10px;
    }
    

    方法二 推荐

    父容器div使用 display:flex; justify-content:space-between; 即可

    html

    <div class="div-container2">
      <div class="div3">3</div>
      <div class="div4">4</div>
    </div>
    

    css

    /* 方法二 */
    .div-container2 {
      margin: 10px 0;
      padding: 10px;
      width: 400px;
      border: 2px solid #ccc;
      display: flex;
      justify-content: space-between;
    }
    .div3 {
      width: 100px;
      height: 50px;
      border: 2px solid red;
    }
    .div4 {
      width: 100px;
      height: 50px;
      border: 2px solid red;
    }
    

    方法三

    父容器div使用display: flex;实现水平排列, 子div设置宽度进行填充占位

    html

    <div class="div-container3">
      <div class="div5">5</div>
      <div class="div7">占位div</div>
      <div class="div6">6</div>
    </div>
    

    css

    /* 方法三 */
    .div-container3 {
      margin: 10px 0;
      padding: 10px;
      width: 400px;
      border: 2px solid #ccc;
      display: flex;
      justify-content: space-between;
    }
    .div5 {
      width: 100px;
      height: 50px;
      border: 2px solid red;
    }
    .div6 {
      width: 100px;
      height: 50px;
      border: 2px solid red;
    }
    .div7 {
      width: calc(100% - 100px - 100px);
      height: 50px;
      border: 1px solid #ccc;
    }
