Question

Is it possible to change the CSS when a link is clicked and return it to its normal state when another link is clicked, changing that CSS, as well?

    <div id="nv_wrap">
        <a class="panel nv7" href="#item8"></a>
        <a class="panel nv6" href="#item7"></a>
        <a class="panel nv5" href="#item6"></a>
        <a class="panel nv4" href="#item5"></a>
        <a class="panel nv3" href="#item4"></a>
        <a class="panel nv2" href="#item3"></a>
        <a class="panel nv1" href="#item2"></a>
    </div>

Answer 1

using jQuery, something like this:

$("#nv_wrap a.panel").click(function(){
    $("#nv_wrap a.clicked").removeClass("clicked"); //returns the old one to its normal state
    $(this).addClass("clicked"); //assigns an additional class to the clicked element.
});
