jquery 支持
CSS 1-3 , 还支持一些自定义的样式 (and
XPath), as part of it's
expression language.
为了能更好的运用CSS请阅读以下相关内容:

Supported, but different
All attribute selectors are written like their XPath counter-parts (in that all attributes should begin with an @ symbol).
- E[@foo] an E element with a "foo" attribute
- E[@foo=bar] an E element whose "foo" attribute value is exactly equal to "bar"
- E[@foo^=bar] an E element whose "foo" attribute value begins exactly with the string "bar"
- E[@foo$=bar] an E element whose "foo" attribute value ends exactly with the string "bar"
- E[@foo*=bar] an E element whose "foo" attribute value contains the substring "bar"
Not supported
jquery only supports selectors that actually select DOM elements - everything else is ignored.
- E:link
- E:visited an E element being the source anchor of a hyperlink of which the target is not yet visited (:link) or already visited (:visited)
- E:active
- E:hover
- E:focus an E element during certain user actions
- E:target an E element being the target of the referring URI
- E::first-line the first formatted line of an E element
- E::first-letter the first formatted letter of an E element
- E::selection the portion of an E element that is currently selected/highlighted by the user
- E::before generated content before an E element
- E::after generated content after an E element
