我的页脚不会停留在页面底部。 我尝试了粘性页脚技巧，但没有好处。
似乎我的页脚下方有空白区域。 调整它的高度没有任何好处。

所以，Kakarott的最后一篇文章有效。
另外，我使用position：relative作为我的Media Query移动开发者，它使我的移动网站使用相同的CSS。
因此，对于台式机和平板电脑，我使用的是位置：绝对和移动：相对。
仅供参考，我使用的是响应式设计。

将您的页脚css更改为：
#footer{
clear: both;
position: absolute;
z-index: 10;
height: 3em;
bottom:0;
background-color:#002664;
width:100%;
}
