Question

我一直在使用startbootstrap的模板来完成任务。我希望页面内容包装器是一个纯色，但我不能让它保持100％的窗口高度，甚至在div中添加更多文本它只会保持粉红色一定高度而不会继续。

我已经尝试了一些修复等，但是当我做某些事情时，页脚不会停留在底部（不是固定的）绝对...它会向上移动。

我已经添加了一个jsdiffle链接..拉伸预览窗口使其看起来更像桌面大小而不是移动。

html {
position: relative;
height: 100%;
min-height: 100%;
}

Answer 1

除了.side-menu之外，在每个地方都将位置更改为相对位置，这样您就可以将页脚调到底部。检查我的代码段中的css文件。

Answer 2

在样式表中将页脚位置从绝对位置更改为相对位置

 .footer {

 position: relative;
  }

Answer 3

将页脚类位置更改为fixed并将页脚类高度添加为容器类的填充（容器 - 流体）

.footer {
      position: fixed;
      bottom: 0;
      width: 100%;
      /* Set the fixed height of the footer here */
      height: 60px;
      line-height: 60px; /* Vertically center the text there */
      background-color: #f5f5f5;
    }
    .container-fluid
    {
      padding-bottom:60px;
    }

容器高度颜色不填充 - 底部的页脚向上移动
