:first-child Selector

Categories: Child Filter

jQuery(':first-child')

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

  • jQuery(':first-child')

    version added: 1.0

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.

    HTML:
    <div>
        <span>John,</span>
        <span>Karl,</span>
        <span>Brandon</span>
    
      </div>
      <div>
        <span>Glen,</span>
        <span>Tane,</span>
        <span>Ralph</span>
    
      </div>
    CSS:
    
      span { color:#008; }
      span.sogreen { color:green; font-weight: bolder; }
      
    Code:
    
        $("div span:first-child")
            .css("text-decoration", "underline")
            .hover(function () {
                  $(this).addClass("sogreen");
                }, function () {
                  $(this).removeClass("sogreen");
                });
