css图片水平居中
利用margin:0 auto;实现图片水平居中
<div style="width: 500px; border: green solid 1px;">
<img alt="" src="https://www.baidu.com/img/baidu_jgylogo3.gif" style="display:block; margin: 0 auto;" />
</div>
利用文本的水平属性text-align:center;
注意:img本身为行内块元素(inline-block)
<div style="text-align: center; width: 500px; border: green solid 1px;">
<img alt="" src="https://www.baidu.com/img/baidu_jgylogo3.gif" style="display: inline-block;" />
</div>
css图片垂直居中
利用高==行高实现图片垂直居中
此方法需要知道父盒子的高度
<div style="text-align: center; width: 500px;height:200px; line-height:200px; border: green solid 1px;">
<img alt="" src="https://www.baidu.com/img/baidu_jgylogo3.gif" style="display: inline-block; vertical-align: middle;" />
</div>
利用绝对定位实现图片垂直居中
需要知道图片的宽度和高度(或者直接使用padding或margin来实现)
<div style="width: 500px;height:200px; position: relative; border: green solid 1px;">
<img alt="" src="https://www.baidu.com/img/baidu_jgylogo3.gif" style="width: 120px; height: 40px;position: absolute; left:50%; top: 50%; margin-left: -60px;margin-top: -20px;" />
</div>
移动端可以利用flex布局实现css图片垂直居中
css代码:
<style type="text/css">
/*web前端开发http://www.51xuediannao.com/*/
.ui-flex {
display: -webkit-box !important;
display: -webkit-flex !important;
display: -ms-flexbox !important;
display: flex !important;
-webkit-flex-wrap: wrap;
-ms-flex-wrap: wrap;
flex-wrap: wrap
}
.ui-flex, .ui-flex *, .ui-flex :after, .ui-flex :before {
box-sizing: border-box
}
.ui-flex.justify-center {
-webkit-box-pack: center;
-webkit-justify-content: center;
-ms-flex-pack: center;
justify-content: center
}
.ui-flex.center {
-webkit-box-pack: center;
-webkit-justify-content: center;
-ms-flex-pack: center;
justify-content: center;
-webkit-box-align: center;
-webkit-align-items: center;
-ms-flex-align: center;
align-items: center
}
</style>
html代码:
<div class="ui-flex justify-center center" style="border: green solid 1px; width: 500px; height: 200px;">
<div class="cell">
<img alt="" src="https://www.baidu.com/img/baidu_jgylogo3.gif" style="" />
