## 两端对齐 ##

.wrap { 
    	width: 400px;
    	display: flex;/*弹性盒子*/
    	justify-content: space-between;/*两端对齐，子元素之间有间隙*/
    	flex-flow: row wrap; /*子元素溢出父容器时换行*/
    }
    
    span { 
    	width: 100px;
    	background-color: green;
    	color: #fff;
    	border-radius: 5px;
    	margin-top: 10px;
    	padding: 10px;
    }

## 解决方法：追加一个空的子元素 ##

.wrap:after { content: ""; width: 120px; }

## 居中对齐 ##
