How to insert the plugin code into the website

Good morning, I have the following code for a single file –
<?php

        <div id="primary" class="content-area">
	<div class="content-container site-container">
		<main id="main" class="site-main" role="main">
			<?php
			/**
			 * Hook for anything before main content
			 */
			do_action( 'kadence_before_main_content' );
			?>
			<div class="content-wrap">
				<?php
				if ( is_404() ) {
					do_action( 'kadence_404_content' );
				} elseif ( have_posts() ) {
					while ( have_posts() ) {
						the_post();
						/**
						 * Hook in content single entry template.
						 */

						do_action( 'kadence_single_content' );
					}
				} else {
					get_template_part( 'template-parts/content/error' );
				}
				?>

			</div>
			<?php			
			/**
			 * Hook for anything after main content
			 */
			do_action( 'kadence_after_main_content' );
			?>

When I add the code, the website does not work properly. How to insert the code into the page content so that it is displayed correctly?
