[JQuery]CSS

What follows is a list of supported CSS Selector expressions.

• * any element
• E an element of type E
• E:root an E element, root of the document
• E:nth-child(n) an E element, the n-th child of its parent
• E:first-child an E element, first child of its parent
• E:last-child an E element, last child of its parent
• E:only-child an E element, only child of its parent
• E:empty an E element that has no children (including text nodes)
• E:enabled
• E:disabled a user interface element E which is enabled or disabled
• E:checked a user interface element E which is checked (for instance a radio-button or checkbox)
• E.warning an E element whose class is "warning"
• E#myid an E element with ID equal to "myid".
• E:not(s) an E element that does not match simple selector s
• E F an F element descendant of an E element
• E > F an F element child of an E element
• E + F an F element immediately preceded by an E element
• E ~ F an F element preceded by an E element

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

jQuery doesn't support the following selectors due to their lack of real-world usefulness:

• E:nth-last-child(n) an E element, the n-th child of its parent, counting from the last one
• E:nth-of-type(n) an E element, the n-th sibling of its type
• E:nth-last-of-type(n) an E element, the n-th sibling of its type, counting from the last one
• E:first-of-type an E element, first sibling of its type
• E:last-of-type an E element, last sibling of its type
• E:only-of-type an E element, only sibling of its type
• E:lang(fr) an element of type E in language "fr"
