以下居中布局均
以不定宽为前提
,定宽情况包含其中
css.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,需要使用css hack 进行兼容
css.child{
display: table;
margin: 0 auto;
}
tips:此方案兼容至IE8,可以使用
<table/>
代替css写法,兼容性良好
css.parent{
position: relative;
height:1.5em;
}
.child{
position: absolute;
left: 50%;
transform: translateX(-50%);
}
tips:此方案兼容至IE9,因为 transform 兼容性限制,如果
.child
为定宽元素,可以使用以下写法,兼容性极佳
css.parent{
position: relative;
height:1.5em;
}
.child{
position: absolute;
width:100px;
left: 50%;
margin-left:-50px;
}
css.parent{
display: flex;
justify-content: center;
}
.child{
margin: 0 auto;
}
tips:flex是一个强大的css,生而为布局,它可以轻松的满足各种居中、对其、平分的布局要求,但由于现浏览器兼容性问题,此方案很少被使用,但是值得期待浏览器兼容性良好但那一天!
css.parent{
display: table-cell;
vertical-align: middle;
}
tips:可替换成
<table />
布局,兼容性良好
css.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
如果是定高(假如高100px),可以使用margin-top: -50px;
。
css.parent{
display: flex;
align-items: center;
}
tips:高版本浏览器兼容,低版本不适用
css.parent{
text-align: center;
display: table-cell;
vertical-align: middle;
}
.child{
display: inline-block;
}
tips:兼容至IE8
css.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
css.parent{
display: flex;
justify-content: center;
align-items: center;
}
tips:兼容差
css.left{
float: left;
width: 100px;
}
.right{
margin-left: 120px;
}
tips:此方案对于定宽布局比较好,不定宽布局推荐下面这个方法
css.left{
float: left;
width: 100px;
margin-right: 20px;
}
.right{
overflow: hidden;
}
tips:个人常用写法,此方案不管是多列定宽或是不定宽,都可以完美实现,同时可以实现等高布局

display: table; width: 100%;
