HTML，CSS - 页脚重叠页面中的内容

时间：2017-09-29 06:55:45

标签： javascript html css

我目前在主页上的页脚有问题。我有一个幻灯片，我尝试从w3school复制粘贴垂直表格代码以检查我的页脚。

我遇到我的页脚在页面底部不是静态的，尽管我已经将位置更改为相对位置。

P.s - 我甚至试过其他类似帖子的解决方案，似乎没有什么对我有用。

真的需要帮助。

在页脚之前有浮动div，你需要清除浮动效果并从页脚移除高度。默认位置的html内容：静态和静态位置顶部/右侧/底部/左侧定位不适用。

请更改此CSS样式。

footer {
    background: #aaa;
    color: #fff;
    text-align: center;
    clear: both; /* clearing floating affects from both left,right sides */
}

您是否尝试在java中使用普通表类型？我觉得这很容易。 

  <table>
  <tr>
        <td>
          add your code here
        </td>
  </tr>

 </table>
