建站老手都知道,这是为了考虑到浏览器的兼容问题,其实不同浏览器对有些标签的默认值是不同的,如果没对CSS初始化往往会出现浏览器之间的页面差异。当然,初始化样式会对SEO有一定的影响,但鱼和熊掌不可兼得,但力求影响最小的情况下初始化。最简单的初始化方法就是: * {padding: 0; margin: 0;} 。有很多人也是这样写的。这确实很简单,但有人就会感到疑问:*号这样一个通用符在编写代码的时候是快,但如果网站很大,CSS样式表文件很大,这样写的话,他会把所有的标签都初始化一遍,这样就大大的加强了网站运行的负载,会使网站加载的时候需要很长一段时间。写过css的都知道每个网页引进的css首先都需要初始化,而出名的css reset有YUI css reset(QQ、淘宝等都出现他的影子),业内用的最多的还有Erik Meyer’s CSS Reset。CSS初始化是指重设浏览器的样式。不同的浏览器默认的样式可能不尽相同,所以开发时的第一件事可能就是如何把它们统一。如果没对CSS初始化往往会出现浏览器之间的页面差异。每次新开发网站或新网页时候通过初始化CSS样式的属性,为我们将用到的CSS或html标签更加方便准确,使得我们开发网页内容时更加方便简洁,同时减少CSS代码量,节约网页下载时间。
