How can I highlight the active link in the page and change the color of the selected links in the page?

I have made a video gallery using videolightbox tool. It has generated query for it to work. I have no idea about any scripting.

I just want to highlight the active link in the page and change the color of the selected links in the page. I sure it can be done.

Also is there a way to bookmark the visited links on the page as external txt file? so that when the page gets loaded next day I still be able to have the visited links high lighted. Hope it can be done too.

jQuery(function () {
    var $ = jQuery;
    var swfID = "video_overlay";
    if (!document.getElementById("vcontainer")) {
        $("body").append($("<div id='voverlay'></div>"));
        $("#voverlay").append($("<div id = 'vcontainer'></div>"));
    }
    $("#vi开发者_Python百科deogallery a[rel]").overlay({
        api: true,
        expose: 0.7 ? {
            color: "#55aaff",

            opacity: 0.7

            swfobject.removeSWF(swfID);
