方法一：position加margin

<div class="wrap">    <div class="center"></div></div>

/**css**/.wrap {    width: 200px;    height: 200px;    background: yellow;    position: relative;}.wrap .center {    width: 100px;    height: 100px;    background: green;    margin: auto;    position: absolute;    left: 0;    right: 0;    top: 0;    bottom: 0;}

兼容性：主流浏览器均支持，IE6不支持

方法二： diaplay:table-cell

<!-- html --><div class="wrap">     <div class="center"></div></div>

/*css*/.wrap{    width: 200px;    height: 200px;    background: yellow;    display: table-cell;    vertical-align: middle;    text-align: center;}.center{    display: inline-block;    vertical-align: middle;    width: 100px;    height: 100px;    background: green;}

兼容性：由于display:table-cell的原因，IE6\7不兼容

方法三：position加 transform

<!-- html --><div class="wrap">    <div class="center"></div></div>

/* css */.wrap {    position: relative;    background: yellow;    width: 200px;    height: 200px;} .center {    position: absolute;    background: green;    top:50%;    left:50%;    -webkit-transform:translate(-50%,-50%);    transform:translate(-50%,-50%);    width: 100px;    height: 100px;}

兼容性：ie9以下不支持 transform，手机端表现的比较好。

方法四：flex;align-items: center;justify-content: center

<!-- html --><div class="wrap">    <div class="center"></div></div>

/* css */.wrap {    background: yellow;    width: 200px;    height: 200px;    display: flex;     align-items: center;     justify-content: center;} .center {    background: green;    width: 100px;    height: 100px;}

移动端首选

方法五：display:flex;margin:auto

<!-- html --><div class="wrap">    <div class="center"></div></div>

/* css */.wrap {    background: yellow;    width: 200px;    height: 200px;    display: flex; } .center {    background: green;    width: 100px;    height: 100px;    margin: auto;}

移动端首选

方法六：纯position

<!-- html --><div class="wrap">    <div class="center"></div></div>

/* css */.wrap {    background: yellow;    width: 200px;    height: 200px;    position: relative;}/**方法一**/.center {    background: green;    position: absolute;    width: 100px;    height: 100px;    left: 50px;    top: 50px;   }/**方法二**/.center {    background: green;    position: absolute;    width: 100px;    height: 100px;    left: 50%;    top: 50%;  margin-left:-50px;  margin-top:-50px;}

兼容性：适用于所有浏览器

方法七：兼容低版本浏览器，不固定宽高

<!-- html --><div class="table">    <div class="tableCell">        <div class="content">不固定宽高，自适应</div>    </div></div>

/*css*/.table {    height: 200px;/*高度值不能少*/    width: 200px;/*宽度值不能少*/    display: table;    position: relative;    float:left;    background: yellow;}       .tableCell {    display: table-cell;    vertical-align: middle;    text-align: center;            *position: absolute;    padding: 10px;    *top: 50%;    *left: 50%;}.content {    *position:relative;    *top: -50%;    *left: -50%;     background: green;}
