基于其中元素的 div 变化高度
原标题:change height of div based on elements within it

基本上 IF div.Pageheader Description 包含 NO img 和 NO div#cat-text ,然后我想将高度为 0px, 这样就不会有白色的空间 。

这是我的CS:"/强"

.PageHeaderDescription {
    height: 320px;
    position: relative;
    width: 99%;
}

< 坚固> 这是 CSS 路径:

html body div#Container div#Content div.PageHeaderDescription

<强 > 下方是 HTML

<div class="PageHeaderDescription">
    <img border="0" src="images/Category/large/22.png" class="c1" />

    <div id="cat-text" class="c2">
      <table>
        <tbody>
          <tr>
            <td>
              <h1>1 Person</h1>
            </td>

            <td><span>test</span></td>
          </tr>
        </tbody>
      </table>
    </div>
  </div>

Is using jquery the best way or could i use clear:both some how? Could you help me, i am not sure how to check for elements in a div using jquery. I know contains works for string values?

最佳回答

您可以使用 cs 高度: 自动

div.PageHeaderDescription {height: auto}
问题回答

你为什么不把“ 最大高度” 设为 320px 320px 。 这样, div 默认会默认为 0 高度, 但必要时会扩展为 320px 最高高度 。

您可以在 CSS 中使用 < code>: noty 选择器:

.PageHeaderDescription:empty {display: none;}
