       因为没有仔细系统学习前端的东西,这两天遇到了一个奇怪的问题,因为要挂上一个飘窗的效果,就是要在网站的首页上加上一个那种浮动的图片,在网上找到了实现这样效果的javascript代码,在本地打开之后,各个浏览器中都能够看到浮动的效果,但是把这段代码复制到自己的首页上就发现没有效果,以为是路径的问题,修改了这些问题之后还是发现不行,后来同学就在老版本的IE中浏览,就发现可以进行浏览,效果和本地一样,这个时候才想到是自己html文档最前边的文档说明
我们首页本来的文档说明是html5的,而我们实在chrome和火狐中浏览的不可以,所以就试着将 先去掉,然后奇迹地发现那个浮动效果有实现了,因为我们找的那段js代码不规范的原因没有符合html5的标准,结果那个效果就没有实现,可见代码规范的重要性.
