How to add a full width slider inside Hueman WordPress Theme?

We all know Hueman is one of the best made WordPress theme. And it is free too.  This theme basically does not have slider in it.  So, I created a child theme called “Hueplus” with slider in it.  However, That slider is not full width.

Hence I modified the code a little more on header.php to have a slider in full width.

You just need to replace the header.php of Hueman WordPress theme with the below code. ( DO NOT FORGET TO BACKUP, it will be useful if anything goes wrong).

<!DOCTYPE html> 
<html class="no-js" <?php language_attributes(); ?>>

<head>
	<meta charset="<?php bloginfo('charset'); ?>">
	<meta name="viewport" content="width=device-width, initial-scale=1.0">

	<title><?php wp_title(''); ?></title>

	<link rel="pingback" href="<?php bloginfo('pingback_url'); ?>">
	
	<?php wp_head(); ?>
</head>

<body <?php body_class(); ?>>

<div id="wrapper">

	<header id="header">
	
		<?php if (has_nav_menu('topbar')): ?>
			<nav class="nav-container group" id="nav-topbar">
				<div class="nav-toggle"><i class="fa fa-bars"></i></div>
				<div class="nav-text"><!-- put your mobile menu text here --></div>
				<div class="nav-wrap container"><?php wp_nav_menu(array('theme_location'=>'topbar','menu_class'=>'nav container-inner group','container'=>'','menu_id' => '','fallback_cb'=> false)); ?></div>
				
				<div class="container">
					<div class="container-inner">		
						<div class="toggle-search"><i class="fa fa-search"></i></div>
						<div class="search-expand">
							<div class="search-expand-inner">
								<?php get_search_form(); ?>
							</div>
						</div>
					</div><!--/.container-inner-->
				</div><!--/.container-->
				
			</nav><!--/#nav-topbar-->
		<?php endif; ?>
		
		<div class="container group">
			<div class="container-inner">
				
				<div class="group pad">
					<?php echo alx_site_title(); ?>
					<?php if ( ot_get_option('site-description') != 'off' ): ?><p class="site-description"><?php bloginfo( 'description' ); ?></p><?php endif; ?>
				</div>
			</div>
		</div>
				<div id="slider-wrap">
					<?php //any slider shortcode can go here ?>
				</div>
		<div class="container group">
			<div class="container-inner">
				<?php if (has_nav_menu('header')): ?>
					<nav class="nav-container group" id="nav-header">
						<div class="nav-toggle"><i class="fa fa-bars"></i></div>
						<div class="nav-text"><!-- put your mobile menu text here --></div>
						<div class="nav-wrap container"><?php wp_nav_menu(array('theme_location'=>'header','menu_class'=>'nav container-inner group','container'=>'','menu_id' => '','fallback_cb'=> false)); ?></div>
