Move Navbar Below Header

well same thing really…go into your home page php (don’t know if you are using the index page or a custom made .php)
and copy and paste the<div class="navigation">section below your slider.
I just tested it on one of my pages.
I copied the mastehead section

<header id="masthead" class="site-header" role="banner">
			<?php if ( get_header_image() ) : ?>
				<div class="hdr-img">
		<a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home">
			<img src="<?php header_image(); ?>" width="<?php echo esc_attr( get_custom_header()->width ); ?>" height="<?php echo esc_attr( get_custom_header()->height ); ?>" alt="">
			</div> <!--  end hdr-img  -->
		<?php endif; // End header image check. ?>
			<div class="site-branding">
				<h1 class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></h1>
				<h2 class="site-description"><?php bloginfo( 'description' ); ?></h2>
			<div class="search"><?php get_search_form(); ?></div><!-- .search -->
			<nav id="site-navigation" class="main-navigation" role="navigation">
				<button class="menu-toggle"><?php _e( 'Primary Menu', 'my_site' ); ?></button>
				<?php wp_nav_menu( array( 'theme_location' => 'primary' ) ); ?>
			</nav><!-- #site-navigation -->
	</header><!-- #masthead -->

And went to my home.php and pasted that below the end of the loop after </main>
it pasted a second copy of the navigation and header image there…
but i guess what i would do instead is copy the slider info in header.php above the navigation menu. Same effect but it would make more sense.
