《css权威指南》与《html5与css3权威指南》那个更权威更先进?
回复内容:
要權威要先進去看W3C文檔http://www.w3.org/standards/webdesign/htmlcss 第一本我没看过,但是第二本内容很多过时的,毕竟出书比较早。当时规范都不明了。
印刷和文笔普通吧。不过书又不贵,都买下来又咋了。 别纠结哪本书了权威了,还是好好静下心来看书吧。 看书其实看目录就大致知道讲什么的了。
- 《CSS权威指南》比较老了,但是由于一些老版本的浏览器还不支持很多CSS3属性,所以用于奠定基础还是值得一看的。(其中关于navigator和IE4,IE5什么的坑可以跳过不看,应该没人会用了)
- 《HTML5与CSS3权威指南》我没看过,初听这个名字还以为是跟《JavaScript权威指南》、《CSS权威指南》一样都是ORelly出的禽兽书,结果不是= =|||。看了目录感觉有些凌乱,给我的第一印象不太好,直观感觉不会是一本好书,亚马逊上的评价也很一般。还是推荐另一本《响应式Web设计:HTML5和CSS3实战》
