Answer 1

fixed now managed to create the effect i was after. after much trial and error here is the code i used for each tab maybe there is a simpler way to do it but this works for now

$(".tour").click(function () {
    $(".hide").hide();
    $(".div2").show();
    $(".tab").addClass("inactive");
    $(".tour").removeClass("inactive");
    $(".tour").addClass("active");

});
