看了一下腾讯ISUX网页，无论是pc端还是移动端，展示都挺好看的，先对其代码进行分析如下：
1，先看前三行代码
<!DOCTYPE html> <!-- 腾讯 ISUX 是腾讯集团核心、全球最具规模的UX设计团队。我们正在招 UI开发、前端开发、客户端开发。快把简历发到 isux@qq.com 吧！ --> <html lang="en-US" prefix="og: http://ogp.me/ns#">
第一行，很正常，目前的网页都这么写的，H5的时代了；
第二行，大公司总要用注释打写广告；
第三行，lang语言居然是en-US，不解，应该没有什么特殊用意吧；prefix属性，百度了一下，用到了ogp协议，ogp主要是为社交媒体用的；
2，head
<head>

<!-- 使用社交媒体（Open Graph、Twitter Cards 和 Schema.org-->
<!-- 与Open Graph相似的还有Twitter的Twitter cards(使用name="twitter:title"或者name="twitter:url")以及Google+使用的Schema.org(使用itemscope和itemprop)。-->
<!-- Open Graph已变得非常受欢迎，所以大多数社交网络默认都是Open Graph。如果Open Graph 的meta标签也没有的话，他们设置缺少meta标签的默认值。-->

3，为了处理移动端展示，最主要的是菜单的隐藏与展示，使用了很多媒体查询，主要是custom.css
4，首页的ITEM如何在屏幕宽的时候展示4个，窄一点又展示三个，2个，1个，主要用到的就是#post-area .masonry-post和媒体查询

5，如何使用微信的JSSDK
注册公众号，然后会有一个AppId和AppSceret
前端代码如下：
<!-- 使用微信JSSDK -->
<script type="text/javascript" src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script type="text/javascript">
jQuery(function($){
// 代码高亮配置
$("pre").addClass("prettyprint linenums");
// prettyPrint();
// 检测wx分享配置数据
// alert("url="+encodeURIComponent(location.href.split('#')[0]));
function wxShareData() {
$.ajax({
type: "GET",
url: "http://www.weichuanghome.com/wx/get.html",
dataType: "text",
data: "url="+encodeURIComponent(location.href.split('#')[0]),
success: function(data) {
var obj = JSON.parse(data);
wx.config({
debug: false, // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。
appId: obj.appId, // 必填，公众号的唯一标识

nonceStr: obj.nonceStr, // 必填，生成签名的随机串

'chooseImage',
] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2
});
wx.ready(function(){
// config信息验证后会执行ready方法，所有接口调用都必须在config接口获得结果之后，config是一个客户端的异步操作，
//所以如果需要在页面加载时就调用相关接口，则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口，
//则可以直接调用，不需要放在ready函数中。

});
},
error: function(jqXHR,textStatus,errorThrown) {
console.log(jqXHR)
console.log(textStatus)
console.log(errorThrown)
}
});
}
wxShareData();
});
