本章节介绍微信weui基础组件中的Flex布局，对于css中的flex什么意思，读者自行查询在这里不在累述。当然如果你不了解也不妨碍你做出案例，只要你按照下面的步骤做即可，咱们重点还是放在微信weui基础组件Flex布局的使用吧。
案例中引用的微信weui的css样式库我已经上传到百度网盘了，地址 http://pan.baidu.com/s/1cvQlLc ，大家可以下载下来进行引用，当然你也可以引用网络地址，但是有个弊端，微信weui的样式库更新比较频繁，可能将来某一天会失效，所以最好下载到本地使用。
一，引入css文件
<link rel="stylesheet" href="https://weui.io/weui.css"> <link rel="stylesheet" href="https://weui.io/example.css">
记得html设置成移动浏览
<meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=0"
二、Flex布局案例html代码
在<body></body>之间添加如下代码
<div class="page flex js_show"> <div class="page__hd"> <h1 class="page__title">Flex</h1> <p class="page__desc">Flex布局(www.vxzsk.com原创)</p> </div> <div class="page__bd page__bd_spacing"> <div class="weui-flex"> <div class="weui-flex__item"><div class="placeholder">weui</div></div> </div> <div class="weui-flex"> <div class="weui-flex__item"><div class="placeholder">weui</div></div> <div class="weui-flex__item"><div class="placeholder">weui</div></div> </div> <div class="weui-flex"> <div class="weui-flex__item"><div class="placeholder">weui</div></div> <div class="weui-flex__item"><div class="placeholder">weui</div></div> <div class="weui-flex__item"><div class="placeholder">weui</div></div> </div> <div class="weui-flex"> <div class="weui-flex__item"><div class="placeholder">weui</div></div> <div class="weui-flex__item"><div class="placeholder">weui</div></div> <div class="weui-flex__item"><div class="placeholder">weui</div></div> <div class="weui-flex__item"><div class="placeholder">weui</div></div> </div> <div class="weui-flex"> <div><div class="placeholder">weui</div></div> <div class="weui-flex__item"><div class="placeholder">weui</div></div> <div><div class="placeholder">weui</div></div> </div> </div> <div class="page__ft j_bottom"> <a href="javascript:home()"><img src="http://weui.io/images/icon_footer_link.png"></a> </div> </div>
三、效果
打开谷歌浏览器，设置手机网页模式浏览案例网页
如上图所示，在这里我们模拟的是苹果6PLUS下的效果。
四、完整html代码
