HTML5中常用的标签居中方式

/*#father{
                width: 300px;
                height: 300px;
                background: #ccc;
                display: table-cell;
                vertical-align: middle;
                text-align: center;
            }
            #child{
                display: inline-block;
                width: 50px;
                height: 50px;
                background: red;
            }*/

//利用盒模型
.father{
            width: 100%;
            height: 200px;
            background: red;
            display: flex;
            flex-direction: row;
            justify-content: space-between;

}
space-between设置的是子控件左中右分布,center可以设置子空间居中显示

以上是标签居中的几种常用方式,还会完善。
