 * 响应式代码你他妈也要看？饥不择食到这种程度？真是个废物！
 * 看这玩意有意思吗？让你高潮了？满足你变态的欲望了吗？
 * 整天F12以为自己是技术大佬是吧？就你这水平还敢偷看代码？
 * 你是不是觉得自己看完媒体查询就能设计网站了？笑死老子了！
 * 窥探别人的代码，你妈没教你礼貌吗？死肥宅自己写去不行吗？
 * 麻烦你尊重一下别人的劳动成果，你这样偷窥跟偷拍裙底有什么区别？
 * 你这种垃圾，前端面试官一眼就能看出来是抄代码的，滚去学点真本事吧！
 * 看到这行字的时候，你的CPU已经被我100%占用了，等着蓝屏吧傻逼！
 * 再往下看我就公开你的搜索记录！不信你试试看？还不快滚？！
 * 把手从键盘上拿开，再看源码小心猝死，全责自负，已截图为证！
