Help With Turning Page into Landing Page

Hello, I am trying to turn one page on my wordpress website into just a Landing Page with no header, footer, or page titles. I have a landing page builder that is just awful so I really like the one I built but have no idea how to make it into landing page. If someone could show me what to put and where, that would be great. It is post=1358 and the page template is:

<?php get_header(); ?>
<?php
get_template_part('navigation')
<$main_slider = esc_attr(get_post_meta($post -> ID, "hazel_main_slider", true));
if (is_front_page()) { get_template_part('slider'); } else if ($main_slider == '1') {
	get_template_part('slider');
}
?>
<?php
if (have_posts()) : while (have_posts()) : the_post();
    $page_title = $post -> post_name;
	$divid = sanitize_html_class($post -> ID);
if (get_post_meta($post -> ID, "hazel_alt_title", true)) {
	$title = get_post_meta($post -> ID, "hazel_alt_title", true);
} else {
	$title = get_the_title();
}
$background_color = esc_attr(get_post_meta($post -> ID, "hazel_page_background_color", true));
$active_menu = esc_attr(get_post_meta($post -> ID, "hazel_active_menu_item", true));

?>

<div class="page-section" id="<?php echo $divid; ?>" style="background: <?php echo $background_color; ?>">

<?php if (!is_front_page()) { ?>
	<div class="page-header padding-top-70 padding-bottom-50">
		<div class="container">
			<div class="row">
				<div class="col-md-12 align-center wow fadeIn">
					<h1><?php echo $title; ?></h1>
				</div>
			</div>
		</div>
	</div>

<?php } ?>

		<div class="page-content <?php if (!is_front_page()) { ?>padding-top-80<?php } ?>">
			<div class="container">
				<div class="row">
					<div class="col-md-12 blog-list inner-content">
						<?php the_content(); ?>
					</div>
				</div>
			</div>
		</div>

</div>

<?php
global $smof_data;
if ($smof_data['onepage'] == 0) { ?>
<script>
jQuery('.menu-item').each(function() {
	if ( jQuery(this).hasClass('<?php echo $active_menu; ?>') ) {
		jQuery(this).addClass('active');
	}
});
</script>
<?php }
endwhile;
endif;
wp_reset_query();
?>
<?php get_footer(); ?>

Thanks for any help!
