Need Slider behind logo and navbar

Hi,

I need your help with putting the slider that I put in the header but need it to be behind the logo and navigation bar so it does not push it down. As you can see in the link everything is down after I added this code in the header:

<?php
if ( is_front_page() )
echo do_shortcode(‘[cycloneslider id=”home”]’);
?>
I’m thinking that it’s a CSS code that needs to be put in the stylesheet but have not been able to figure it out. Could you please help with this.

Many thanks,

Victor
