IE9真的支持CSS3和HTML5?

微软昨天在其2009年专业开发者大会上展示 了下一个版本的Internet Explorer浏览器IE9。

尽管只是一个早期版本,IE开发团队还是比较高调的宣布了IE9的一些改 进,比如速度比之前的IE版本都更快些,缩小与FF和webkit之间的差距(也就是还是赶不上了?),支持CSS3的一些新特性,比如圆角 (border-radius),不过现在还不清楚是原生支持还是使用私有属性-ms-border-radius。可喜的是,IE9已经可以支 持大部分CSS 选择器了!IE开发团队展示了IE9在css3.info的一个CSS 选择器的测试页面的测试结果。

测试结果显示,IE9支持43个选择器中的41个(另外两个中一个有bug, 一个不支持),在578项测试中通过了574项,这是IE浏览器历史上最大的进步……

虽然微软之前宣布将支持HTML5,但是此次IE开发 团队并未给出一个明确的答案,据说,关于是否支持HTML5,他们还在讨论中……

另外在Windows 7中引入的direct2D和directWrite等GPU硬件加速技术,也将在IE9中使用。

好吧,事实上,从泄漏出的这些信息可以看 出来,IE9相对于IE8,无论在速度还是性能,以及对网站标准的支持,都有很大很大的进步。但是我们或许可以预见:将来某个时候发布的微软的IE9浏览 器,已经远远落后于现在的firefox和chrome/safari了!

但是无论如何,前端观察都会一直关注微软的动静,毕竟大蛋糕在人 家手里——这是一个杯具……

I imply, I know it was my option to learn, however I actually thought youd have something interesting to say. All I hear is a bunch of whining about something that you may fix for those who werent too busy in search of attention.
