css - 如何使用 CSS 制作粘性页脚？

Question

我想将页脚放在页面底部。我试试这个

position: absolute;
left: 0;
bottom: 0;
height: 100px;
width: 100%;

但是我的页脚变得凌乱了。我的网站是用 WordPress 制作的。如果可能的话，我不想为此使用任何插件。我只想使用纯 CSS。

这里是 CSS 脚本

footer #bottom-footer{
background: none repeat scroll 0 0 #FFFFFF;
color: #000000;
border-top: 5px solid #F80000;
text-align: left;
padding: 9px;
font-size: 13px;
}
.footer-wrap a{
color:#000000;
}
.footer-wrap a:hover{
color:#F80000;
}
.footer-logo a {
margin-bottom: 6px;
display: block;
}
.footer-socials {
float: left;
line-height: 0px;
}
.footer-socials a {
border-radius: 100%;
color: #ffffff;
display: inline-block;
font-size: 14px;
height: 30px;
line-height: 30px;
margin-left: 3px;
text-align: center;
vertical-align: middle;
width: 30px;
}

按照从不再可用的在线资源(死链接)实现的干净方法，您的页面应该需要的最少代码是(注意 - 可能最好使用 #bottom-footer用于选择页脚的 footer #bottom-footer - 这可能是问题的一部分):

html {
    position: relative;
    min-height: 100%;
}
body {
    margin: 0 0 100px; /* bottom = footer height */
}
#bottom-footer {
    position: absolute;
    left: 0;
    bottom: 0;
    height: 100px;
    width: 100%;
}
