实现横向滚动有多种实现方式，之前做过实现横向滚动，有一种方式更快捷、更方便实现横向滚动，其中一点关于对子元素的flex-shrink理解。在父元素设置display:flex后，子元素默认flex-shrink: 1;，当子元素的宽度width之和大于屏幕宽度width之后是无法实现滚动的，这时需要在子元素上flex-shrink: 0;

CSS **

    /* 父元素 */
    .scroll {
        display: flex;
    }
    /* 子元素 */
    .item {
        /* width: 100px; */
        width: 100px;
        height: 50px;
        margin-right: 10px;
        background-color: gray;
        border-right: 1px solid;
        text-align: center;      
        flex-shrink: 0;
        line-height: 50px;
    }
