                    </div>
              <div style="float: left; width: 775px; word-wrap: break-word; text-align: justify;" >
                        <span style="font-size:12pt">
                            <span style="font-size:14.0pt">test content test content test content test content test content test content.</span>

只需将overflow: auto添加到红色背景的div:

<div class="" style="background-color:red; clear: both;padding-top:10px;overflow:auto" id="test">
  <div style="float:left;">
    <input type="checkbox" class="chk" style="display: none;">
  </div>
  <div style="width:946px;">
    <div class="portlet-content" style="background-color:blue;">
      <div style="float: left; padding-right: 10px; text-align: right; padding-left: 25px;">
        <b><span style="font-size:11.0pt">4)</span></b>
      </div>
      <div style="float: left; width: 775px; word-wrap: break-word; text-align: justify;">
        <span style="font-size:12pt">
                            <span style="font-size:14.0pt">test content test content test content test content test content test content.</span>
        </span>
      </div>
    </div>
  </div>
</div>

当你浮动一个子元素时,父元素的容器会崩溃,就好像孩子没有占用空间一样。

如果您将该属性添加到overflow: auto

的CSS中,

div应该可以解决问题

使用clear div添加此代码。

<div class="" style="background-color:red; clear: both;padding-top:10px;" id="test">
   <div style="float:left;">
          <input type="checkbox" class="chk" style="display: none;">
     </div>
      <div style="width:946px;">
        <div class="portlet-content" style="background-color:blue;">
           <div style="float: left; padding-right: 10px; text-align: right; padding-left: 25px;" >
                <b><span style="font-size:11.0pt">4)</span></b>
                </div>
          <div style="float: left; width: 775px; word-wrap: break-word; text-align: justify;" >
                    <span style="font-size:12pt">
                        <span style="font-size:14.0pt">test content test content test content test content test content test content.</span>
                    </span>
                </div>
                <div style="clear:both; display:block;"></div>
            </div>
        </div>
    </div>
