再写点样式就行

        *{

            padding: 0;
        }
        .box{
            width: 500px;
            height: 500px;
            display: flex;
        }
        .r{
            flex: 1;
            background: saddlebrown;
        }
        .l{
            flex: 1;
            height: 100%;
        }
        .lT{

        .lB{

            <div class="lB"></div>
        </div>

        <meta name="viewport" content="width=device-width, initial-scale=1">

        <div class="box">

                <div class=""> </div>
            </div>
        </div>
    </body>
</html>

用flex布局

<style>
.main{display:flex;}
.main>div{width:50%;}
</style>
<div class="main">
  <div class="bigImg"></div>
  <div class="tImg">
    <div class="sImg"></div>
  <div class="bigImg"></div>
  </div>
</div>

首先要非常感谢大虾的帮助，特别是楼上两位，后面还提供了完整的代码图。可能淘宝的代码区和html的代码不兼容的原因。尝试了无数次还是没有成功。一个小白上传个格式真不容易。谢谢大家！
