【问题描述】：
Stack Overflow 上的各位读者朋友，我目前正在使用 CSS，我遇到了麻烦，我将容器的最小高度设置为 100%，以使我的页脚位于页面底部，而不是更高。
*{
margin:0;
padding:0;
}
html,body{
margin:0;
padding;0;
height:100%;
}
body{
font-family:Verdana, Helvetica, Arial, sans-serif;
font-size:12px;
color:#EFEFEF;
background:url(../img/bg.jpg);
}
#container{
width:1150px;
opacity:0.7;
background-color:black;
min-height:100%;
margin:auto;
}
/* Main Navigation */
#main-nav { height: 50px; }
#main-nav dl { margin: 0; padding: 0; }
/* IE5 Mac Hack \*/
#main-nav { padding-left: 11px; }
/*/
#main-nav { padding-left: 11px; overflow: hidden; }
/* End Hack */
#main-nav dt { float: left; }
#main-nav dt a {
display: block;
height: 0px !important;
height /**/:50px; /* IE 5/Win hack */
padding: 50px 0 0 0;
overflow: hidden;
background-repeat: no-repeat;
}
#main-nav dt a:hover {
background-position: 0 -50px;
}
#main-nav dt#about,
#main-nav dt#about a { width: 71px; background-image: url(../img/nav/about.gif); }
#main-nav dt#services,
#main-nav dt#services a { width: 84px; background-image: url(../img/nav/services.gif); }
#main-nav dt#portfolio,
#main-nav dt#portfolio a { width: 95px; background-image: url(../img/nav/portfolio.gif); }
#main-nav dt#contact,
#main-nav dt#contact a { width: 106px; background-image: url(../img/nav/contact.gif); }
body.about dt#about,
body.about dt#about a,
body.about dt#about a:hover,
body.services dt#services,
body.services dt#services a,
body.services dt#services a:hover,
body.portfolio dt#portfolio,
body.portfolio dt#portfolio a,
body.portfolio dt#portfolio a:hover,
body.contact dt#contact,
body.contact dt#contact a,
body.contact dt#contact a:hover {
background-position: 0 -100px;
}
body.about #header {
height: 150px;
background: #db6d16
url(../img/headers/about.jpg);
}
#header{
height:150px;
background:#DB6D16 url(../img/headers/about.jpg);
}
#header h1{
margin:0;
padding:0;
float:right;
margin-top:57px;
padding-right:31px;
}
#sidebar{
float:right;
width:280px;
line-height:18px;
}
#content{
margin-right:280px;
line-height:18px;
}
#footer{
height:100px;
clear:both;
font-family:Tahoma, Arial, Helvetica, sans-serif;
font-size:10px;
color:#C9C9C9;
border-top:1px solid #EFEFEF;
padding:13px 25px;
line-height:18px;
margin-top:-100px;
position:relative;
}
#footer a{
color:#C9C9C9;
text-decoration:none;
}
#footer a:hover{
color:#DB6D16;
}
#footer #altnav{
width:350px;
float:right;
text-align:right;
}
#main{
overflow:auto;
padding-bottom:100px;
}
.hidden{
display:none;
}
#content h2{
margin:0;
padding:0;
padding-bottom:15px;
}
#content p{
margin:0;
padding:0;
padding-bottom:15px;
}
#sidebar .padding, #content .padding{
padding:25px;
}
这是我用的CSS，效果是：http://picpaste.com/e85f01c1b470e03c36988c1487917add.png 所以，如果你看图片，我希望页脚（白线以下的所有内容）位于最底部，页脚上方的所有内容（内容、侧边栏、页眉、菜单）连接到顶部页脚。
如果需要更多信息，请询问！

【问题讨论】：
-
方便的是您的 html 的 sn-p 将所有内容布置到
#container元素，但很可能您的容器位于没有定义高度的元素中。 -
我已经编辑了帖子并包含了 HTML。 ;)
-
我看到你找到了答案。作为旁注；您将
#container设置为 70% 的不透明度。虽然这很好，但您可能应该查看 rgba 背景和过滤器属性以支持 IE nickcowie.com/2009/rgba-backgrounds-in-ie
