咱们在平常开发中常常遇到布局问题,下面罗列几种经常使用的css布局方案
话很少说,上代码!css

如下居中布局均以不定宽为前提,定宽状况包含其中css3
.parent{ text-align: center; } .child{ display: inline-block; }
tips:此方案兼容性较好,可兼容至IE8,对于IE567并不支持inline-block,须要使用css hack进行兼容git
.child{ display: table; margin: 0 auto; }
tips:此方案兼容至IE8,可使用<table/>
代替css写法,兼容性良好github
.parent{ position: relative; height:1.5em; } .child{ position: absolute; left: 50%; transform: translateX(-50%); }
tips:此方案兼容至IE9,由于transform兼容性限制,若是.child
为定宽元素,可使用如下写法,兼容性极佳segmentfault
.parent{ position: relative; height:1.5em; } .child{ position: absolute; width:100px; left: 50%; margin-left:-50px; }
.parent{ display: flex; justify-content: center; } .child{ margin: 0 auto; }
tips:flex是一个强大的css,生而为布局,它能够轻松的知足各类居中、对其、平分的布局要求,但因为现浏览器兼容性问题,此方案不多被使用,可是值得期待浏览器兼容性良好但那一天!浏览器
.parent{ display: table-cell; vertical-align: middle; }
tips:可替换成<table />
布局,兼容性良好app
.parent{ position: relative; } .child{ position: absolute; top: 50%; transform: translateY(-50%); }
tips:存在css3兼容问题,定宽兼容性良好布局
.parent{ display: flex; align-items: center; }
tips:高版本浏览器兼容,低版本不适用flex
a) inline-block + table-cell + text-align + vertical-align
.parent{ text-align: center; display: table-cell; vertical-align: middle; } .child{ display: inline-block; }
tips:兼容至IE8
b) absolute + transform
.parent{ position: relative; } .child{ position: absolute; left: 50%; top: 50%; transform: translate(-50%,-50%); }
tips:兼容性稍差,兼容IE10以上
c) flex
.parent{ display: flex; justify-content: center; align-items: center; }
tips:兼容差
a) float + margin
.left{ float: left; width: 100px; } .right{ margin-left: 120px; }
tips:此方案对于定宽布局比较好,不定宽布局推荐方法b
b) float + overflow
.left{ float: left; width: 100px; margin-right: 20px; } .right{ overflow: hidden; }
tips:我的经常使用写法,此方案不论是多列定宽或是不定宽,均可以完美实现,同时能够实现登高布局

【方案】圣杯布局&双飞翼布局
【JsFiddle】
https://jsfiddle.net/zwwill/px57xzp4/
<div class="container"> <div class="header">header</div> <div class="wrapper clearfix"> <div class="main col">main</div> <div class="left col">left</div> <div class="right col">right</div> </div> <div class="footer">footer</div> </div>
.container {width: 500px; margin: 50px auto;} .wrapper {padding: 0 100px 0 100px;} .col {position: relative; float: left;} .header,.footer {height: 50px;} .main {width: 100%;height: 200px;} .left {width: 100px; height: 200px; margin-left: -100%;left: -100px;} .right {width: 100px; height: 200px; margin-left: -100px; right: -100px;} .clearfix::after {content: ""; display: block; clear: both; visibility: hidden; height: 0; overflow: hidden;}
ps:
“这不是同样的图嘛?”
“对!就是同样的,由于是解决同一种问题的嘛。”

本身瞎搞的,简单的绝对定位便可解决问题,为啥还要搞什么圣杯和双飞翼

<div class="header">header</div> <div class="wrapper"> <div class="main col"> main </div> <div class="left col"> left </div> <div class="right col"> right </div> </div> <div class="footer">footer</div>
.wrapper { position: relative; } .main { margin:0 100px;} .left { position: absolute; left: 0; top: 0;} .right { position: absolute; right: 0; top: 0;}
