## 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)`.

### Example:

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

    <!DOCTYPE html>
    <html>
    <head>
      <style>
      span { color:#008; }
      span.sogreen { color:green; font-weight: bolder; }
      </style>
      <script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
    </head>
    <body>
      <div>
        <span>John,</span>
        <span>Karl,</span>
        <span>Brandon</span>

      </div>
      <div>
        <span>Glen,</span>
        <span>Tane,</span>
        <span>Ralph</span>

      </div>
    <script>
        $("div span:first-child")
            .css("text-decoration", "underline")
            .hover(function () {
                  $(this).addClass("sogreen");
                }, function () {
                  $(this).removeClass("sogreen");
                });

    </script>

    </body>
    </html>
