前端显示技术问题
www.   cc178.   cn/ 这个站pc和手机端显示不同，但是view-source:https://www.   cc178.   cn/ 手机和pc源代码是一样的。有知道怎么实现的么。
很奇怪还用了iframe

view-source:源代码是正常网站数据

pc打开就是一个正常页面

wuguou6

有谁了解过如何实现这种效果吗
感觉是前端js弄的

媒体查询是CSS 3的一项功能，允许内容呈现适应不同的条件，例如屏幕分辨率。它在2012年6月成为W3C推荐的标准，并且是响应式Web设计的基础技术

他这个是JS或者后端控制

他混淆过了，核心代码如下：

很奇怪 谷歌浏览器切换移动端 用的手机分辨率 还是回显示pc界面
但是用安卓手机就会显示手机界面

说明不只是分辨率技术 还有啥其他配置

应该就是这个方法，大佬你这个js在哪里找出来的 我没找到
if (/Android|iPhone|iPad|iPod/i.test(navigator.platform)) {
  // 当前设备是移动设备
}

科技

判断不是移动设备就js写入 iframe覆盖代码

是不是这种效果
