解决UC浏览器或微信浏览器上flex兼容问题

在UC浏览器上使用display:flex;时会不起作用,要加上兼容性写法,如下

display: -webkit-box;      /* OLD - iOS 6-, Safari 3.1-6 */
            display: -moz-box;         /* OLD - Firefox 19- (buggy but mostly works) */
            display: -ms-flexbox;      /* TWEENER - IE 10 */
            display: -webkit-flex;     /* NEW - Chrome */
            display: flex;

使用flex:1;时也要添加如下兼容性写法:

-webkit-box-flex: 1;      /* OLD - iOS 6-, Safari 3.1-6 */
            -moz-box-flex: 1;         /* OLD - Firefox 19- */
            width: 20%;               /* For old syntax, otherwise collapses. */
            -webkit-flex: 1;          /* Chrome */
            -ms-flex: 1;              /* IE 10 */
            flex: 1;                  /* NEW, Spec - Opera 12.1, Firefox 20+ */

但是,一定要注意:如果作用于flex:1的元素为input或button时,只用flex:1;是不起作用的,还要加上display:block;才能起作用。

以下为小案例
