如何压下页面的页脚以使其始终包裹在左侧？

标签： html css

我制作了一个左侧有菜单的页面，页面其余部分有一些内容，底部有一个页脚。

一切都很完美如果我有一个很大的文字内容作为内容，因为这将推下页脚，它将使页脚围绕左边环绕菜单。这样，一切都看起来和我的工作完全一样。

然而，当内容只是一个小段落时，页脚没有被推得足够，它只是挂在菜单的右边，就像内容一样。

这是我的问题的SSCCE：

* {

#menu-box {
    margin-left: 5px;
    margin-top: 5px;
    background-color: #E0E0E0;
    float: left;
    overflow: auto;
    width: 120px;
}

#menu-box .menu-category {

有什么办法可以让页脚位于菜单框下方，无论页面上有多少内容？

感谢。

PS：我在这个网站上有jQuery和jQueryUI，所以如果这些库可以提供某种解决方案，我可以使用它。

#footer {
    margin-bottom: 10px;
    padding: 10px;
    border-top: 1px solid #909090;
  clear:both;
}

这就是你需要的。编辑css中的#footer，并使用clear:both;进行更新。这将使它在所有浮动元素下面渲染，在这种情况下是左侧菜单。

只需将clear: left;添加到页脚。

* {
	border:0;
	margin:0;
	padding:0;
}

#menu-box {
    margin-left: 5px;
    margin-top: 5px;
    background-color: #E0E0E0;
    float: left;
    overflow: auto;
    width: 120px;
}

#menu-box .menu-category {
    font-weight: bold;
    padding-left: 10px;
    border-bottom: 1px solid #000000;
}

#menu-box .menu-item {
    padding-left: 20px;
    text-decoration: none;
}

#menu-box .menu-item a {
    text-decoration: none;
}

#menu-box .menu-item a:hover {
    text-decoration: underline;
}

#menu-box .selected {
    font-weight: bold;
    color: #000000;
}

#content
{
	margin-bottom: 15px;
    margin-left: 140px;
}

#footer {
	clear: left;
    margin-bottom: 10px;
	padding: 10px;
    border-top: 1px solid #909090;
}

只需在<br style="clear:both">

之前添加<div id="footer">即可
