Just as friendly advice, if you are a beginner with HTML and CSS, You probably dont want to do this.. if just a beginner with PHP… you should be alright…
look in the appearance – editor – footer.php file…
you will want to copy
<nav id=”access” role=”navigation”>
<?php wp_nav_menu( array( ‘theme_location’ =<‘primary_nav’, ‘container_id’ => ‘primary-nav’, ‘container_class’ =>’nav’, ‘fallback_cb’ =>’minimatica_nav_menu’ ) ); ?>
</nav>
place it in the header.php according to where and how you would like to style it.
