水平垂直居中常见方式总结

html结构为:

<div class="parent">    <div class="child"></div></div>

 

(1)父元素相对定位,子元素关键在于设置为绝对定位,margin:auto

.parent{    width:400px;    height:400px;    background:#afa;    position:relative;}.child{    position:absolute;    left:0;    bottom:0;    right:0;    top:0;    margin:auto;    background:yellow;    width:100px;    height:100px;}

(2)父元素相对定位,子元素绝对定位,且设置transform:translate(-50%,-50%)

.parent{    width:400px;    height:400px;    background:#afa;    position:relative;}.child{    position:absolute;    left:50%;    top:50%;    transform:translate(-50%,-50%);    background:yellow;    width:100px;    height:100px;}

(3)父元素设置为display:flex;justify-content:center;align-items:center

.parent{    width:400px;    height:400px;    display:flex;    justify-content:center;    align-items:center;    background:#afa;}.child{    width:100px;    height:100px;    background:yellow;}

 (4)设置父元素display:table-cell;text-align:center;vertical-align:center;子元素:display:inline-block;

.parent{    display:table-cell;    width:400px;    height:400px;    background:#afa;    text-align:center;    vertical-align: middle;}.child{    display:inline-block;    width:100px;    height:100px;    background:yellow;}
