如何修复它

将主div的height设置为100到

在第二个子div上放置一个宽度。您还需要在该字符串中放置一个空格，因为它不能跨行缠绕

   <div style="width: 800px;border:1px solid black">
          <div style="width:100px;height:100px;float:left;border:1px solid black"></div>
          <div style="float:left">ssdfsdfsdfsdgfag25w6a4g8w5614w5sge16dgf45d4sdffffffffffffffffffffffffffffffffffffffffffffffffffffff5s4f64s6f456a46f456a456456456f456we4f54we5gf45456v4sd5646sadf54s56f465as4f564as56f</div>
          <div style="clear:both"></div>
    </div>

我不想设置主分区的高度

 <div style="width: 800px;border:1px solid black">
          <div style="width:100px;height:100px;float:left;border:1px solid black"></div>
          <div style="float:left; width: 100px">ssdfsdfsdfsdgfag25w6a4g8w5614w5sge16dgf45d4sdffffffffffffffffffffffffffffffffffffffffffffffffffffff5s4f64s6f456a46f456a456456456f456we4f54we5gf45456v4sd5646sadf54s56f465as4f564as56f</div>
          <div style="clear:both"></div>
    </div>
