Hook content positioning / bottom margin

Hi Tom
I am trying to use the Before Header hook to place a slider immediately above the primary navigation. I am using the code:

<?php if ( is_page( 'Home' ) ) : ?>
[cycloneslider id="fp-header"]
<?php endif; ?>

The trouble is that the slider is left aligned and there is a margin between it and the navigation. The site is here: https://www.allanjackson.net/staging1/ Setting the site with a single container and no padding or spacing doesn't seem to eliminate the gap.

Could you suggest solutions?
Thanks
