Help - problem with header and CSS

Hi, I managed to get a GC app working and everything display correctly with the provided our_template view.

I've tried several times to create a header with a navigation menu.

Correct me if I'm wrong, but I gather the proper way to do this in the controller is:

    function _example_output($output = null)
    {
        $this->load->view('header.php');
        $this->load->view('our_template.php',$output);    
    }

Every navigation menu that I have found inevitably uses a CSS file.

The problem is that the CSS file then messes-up the output from our_template.

I've tried several different menus with different CSS files and they alway mess-up the GC output in one way or another.

The last menu/css that I tried was from metroui.

Even if I leave out the header and simply include the metroui CSS file (metro-bootstrap.css) in our_template, I can see it messes up the sizes of the dialogue boxes when adding/editing a record. There are probably other things that I have not noticed yet.

How can I solve this?

Am I using the right method to add a header?

Is there an HTML statement that says "quit using the previously defined CSS rules" so that the GC output will stop using that CSS from the header?

Thanks
