first-child selector
Description: Selects all elements that are the first child of their parent.
jQuery(':first-child')
version added: 1.1.4
While :first matches only a single element, the :first-child selector can match more than one: one for each parent. This is equivalent to :nth-child(1).
Examples
Finds the first span in each matched div to underline and add a hover state.
$("div span:first-child")
.css("text-decoration", "underline")
.hover(function () {
$(this).addClass("sogreen");
}, function () {
$(this).removeClass("sogreen");
});
