I was wondering how I would add the ability to add a highlight box the nav bar on the page your currently on. You know so people know what page their on.

Very much like

    You can use the jquery function window.location.href to compare the site you are on right now with your href of < a > in the list element. For example, "index.html":

    <li><a href="index.html">Home</a></li>
    

    The code below searches for the href of the active page in the list elements < a >. Then adds the class "active" with addClass('active') to the active pages < a > so that you can now call it via CSS. Put this code in the head of your html file.

    <script src="http://code.jquery.com/jquery-2.1.4.min.js"></script>
    <script>
        $(function(){
            $('a').each(function(){
                if ($(this).prop('href') == window.location.href) {
                    $(this).addClass('active'); $(this).parents('li').addClass('active');
                }
            });
        });
    </script>
    

    You can now add your css conditions like changing the color:

    #nav_bar .active {
        color:            #F8F8F8;
        background-color: #4f81bd;
    }

    I somewhere found a pretty simple code to do it.

    <script>
        $(function () {
            $('nav li a').filter(function () {
                return this.href === location.href;
            }).addClass('active');
        });
    </script>

    If you have the same navigation bar in each HTML page of your website, then you can do like this:
    For example in index.html add class='active-page' to the first menu item:

    <div id="nav_bar">
        <ul>
            <li><a href="index.html" class='active-page'>Home</a></li>
            <li><a href="status.html">Status</a></li>
            <li><a href="info.html">Info</a></li>
    

    Then in the status.html add class='active-page' again but for the second item:

    <div id="nav_bar">
        <ul>
            <li><a href="index.html">Home</a></li>
            <li><a href="status.html" class='active-page'>Status</a></li>
            <li><a href="info.html">Info</a></li>
    

    And do this for all of your pages.

    Finally in your css write a class for active-page like this:

    #nav_bar ul li a.active-page
    {
      background-color:blue;
    }
