雷迪森安的乡亲们，欢迎来到老实人的前端课堂，你是不是常常会因为自己写的代码朴实和无华而感到伤心难过呢，不要悲伤不要难过，这我们就来写点帅气逼人的代码。

这里同学们重点学习下编程思想。
做好的网页效果,如何通过发链接给别人看?
1.1解决部署上线~> 部署上线工具(永久免费使用)
1.不需要买服务器就能部署线上,全世界都能访问你的连接啦, 这里给大家推荐一个程序员必备神器~ 简单易懂, 简直神器 ~ 需要源码或者部署神器可在我公z号：前端老实人获取
2.就是把你的代码效果做好了以后, 部署到线上, 把链接发给别人, 就可以让对方通过你的连接点击进去, 就能看到你的网页效果啦, 电脑端和手机端都可以噢! (不然别人看你的网页都要发文件过去,体验感不太好~)
