:first-child Selector

first-child selector

version added: 1.1.4jQuery(':first-child')

Description: Selects all elements that are the first child of their parent.

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).


Finds the first span in each matched div to underline and add a hover state.

<!DOCTYPE html>
  span { color:#008; }

  <script src="http://code.jquery.com/jquery-latest.js"></script>


    $("div span:first-child")
        .css("text-decoration", "underline")
        .hover(function () {
            }, function () {
