CSS Reset的历史(一)
- sprite.evan - 黑客志当艺术家开始准备创作一幅新的画作时,他们不会先去拿镉红或是酞菁蓝的颜料,而是会首先准备好一张新的画布,为什么. 因为对于他们来说,首先需要确保新画布足够平展并且洁净. 许多Web设计师也喜欢使用CSS Reset来”准备“他们的浏览器画布,以确保他们的设计能够在不同的浏览器和系统下拥有同样的呈现. 这篇文章是关于CSS reset的系列文章的第一篇.
我们知道不同的浏览器客户端默认对css的解析会有区别,这种区别是内置到浏览器中的,也就是浏览器客户端会有其本身的一套css来解析默认的页面,如果 IE/Firefox/Chrome 每个版本的默认样式表都是一致的,那么我们的重置样式可以基于这些浏览器内置的样式,理论上将是不是渲染速度会更快一些呢?实际情况可能并不是这样子,包括IE 他们的不同版本的默认css也是不一样的.如下:
