Description: Selects all direct child elements specified by "child" of elements specified by "parent".
As a CSS selector, the child combinator is supported by all modern web browsers including Safari, Firefox, Opera, Chrome, and Internet Explorer 7 and above, but notably not by Internet Explorer versions 6 and below. However, in jQuery, this selector (along with all others) works across all supported browsers, including IE6.
The child combinator (E > F) can be thought of as a more specific form of the descendant combinator (E F) in that it selects only first-level descendants.
