Template problem on single event page

Looks likes there is a need to add HTML block in single-event.php. I use Kleo theme.

<section class="container-wrap main-color">
<div id="main-container" class="container">
<div class="row">
etc

I added theses line to the code to fit with my template, is it an elegant way ? this is my first improvisation with WP coding. For the moment it’s works 🙂

<?php

 /**
 * Template for displaying a single Event
 * You can copy this file to your-theme
 * and then edit the layout.
 */

wp_register_script( 'google-maps-api', 'http://maps.google.com/maps/api/js?sensor=false' );

get_header();
//get_sidebar( 'left-sidebar' );
dynamic_sidebar( 'left-sidebar' );

function pp_single_map_css() {
	echo '<style type="text/css"> .single_map_canvas img { max-width: none; } </style>';
}
add_action( 'wp_head', 'pp_single_map_css' );

wp_print_scripts( 'google-maps-api' );

?>

<section class="container-wrap main-color">
<div id="main-container" class="container">
<div class="row">
<div class="template-page col-sm-9 col-sm-push-3 tpl-left content-area with-meta">
	<div class="wrap-content">
			<div class="container">

[...]

<div class="sidebar sidebar-main sidebar-left col-sm-3 col-sm-pull-9">
	<div class="inner-content widgets-container">
		<?php if ( ! dynamic_sidebar() ) : ?>
			<li>{static sidebar item 1}</li>
			<li>{static sidebar item 2}</li>
		<?php endif; ?>
	</div>
</div>
