Weird Problem…

Weird problem here

View: https://www.liamzdevbox.com

The “Posts” somehow above the nav bar, why is this?

.......
<div id="nav">
<?php wp_nav_menu(); ?>
</div>
<div id="container">
<?php global $wp_query; $total_pages = $wp_query->max_num_pages; if ( $total_pages > 1 ) { ?>
<div id="nav-above" class="navigation">
<p class="nav-previous"><?php next_posts_link(__( '<span class="meta-nav">?</span> older articles', 'liamzdevbox' )) ?></p>
<p class="nav-next"><?php previous_posts_link(__( 'newer articles <span class="meta-nav">?</span>', 'liamzdevbox' )) ?></p>
</div>
<?php } ?>
<?php while ( have_posts() ) : the_post() ?>
.......

Some code to look at.. i can’t see where i’ve gone wrong.
