HTML5 新元素标签系列:HTML5 页面中用的重设样式表(CSS)

所有浏览器对它们“知道”的元素都有默认的设定——元素有多少留白padding和边距margin,它是显示为块还是行内元素?除非用CSS重写这些设定,不然它们就会默认生效。

以下的CSS可以帮助你清除这些默认样式,使你能够按照自己的方式定制样式。

几点说明:

1, 移除了  <acronym>, <center>  <big> 等 HTML5 不再支持的元素。

2,添加了新的 HTML5 元素标签。

3,给应该显示为块的元素显式的添加了 display:block 。(不然的话,一些新的HTML5标签可能在不同浏览器出现奇怪问题)

4,给 <abbr> 和 <dfn> 这两个 HTML5 新元素添加了属性选择,这样的话,只有当它们有 Title 属性时,样式才起作用。
