Question

我正在尝试在母版页上创建一个页脚div。它有点工作，但是当我运行我的网站时，我的页脚下面有很多未使用的空间。我怎么能删除它？我正在使用vs2012。出于某种原因，我不能在工作中使用jsfiddle。对不起，很长的帖子。

Answer 1

从body：

删除以下规则

min-height: 768px;

您的line-height也有footer。删除它以完全删除页脚后的空格（FIDDLE DEMO）。您可以根据需要添加padding-top: 10px;来设置页脚样式。

Answer 2

就像计算机问题的情况一样，它正是你所说的那样，但这不是你想要的！ ;)

CSS文件的min-height部分中的body属性设置为768px。因此，网页的长度始终至少为768px - 如果内容不足，则只会在页脚的其他空白处标记。

要解决您的问题，请减少或删除min-height。

Answer 3

将页脚h3的高度设置为30px

Answer 4

尝试添加：

position: absolute;
bottom: 0px;

到您的页脚css

我的页脚“div”下面有很多未使用的空间
