Twenty Thirteen – Full Width

Hi there – I would like to make the content span the full width of the page on all the pages of my site. I attempted to follow the instructions here: http://ww.wp.xz.cn/support/topic/full-width-page-template-2?replies=26
but it isnt working. Not sure what I am doing wrong. Can anyone help?

added this code to my style.css in child theme:

.entry-header-full,
.entry-content-full,
.entry-summary-full,
.entry-meta-full {
	margin: 0 auto;
	max-width: 1110px;
	width: 100%;
}

copied page.php from theme to child theme, changed the name and added “-full” to the entries above:

get_header(); ?>

	<div id="primary" class="content-area">
		<div id="content" class="site-content" role="main">

			<?php /* The loop */ ?>
			<?php while ( have_posts() ) : the_post(); ?>

				<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
					<header class="entry-header-full">
						<?php if ( has_post_thumbnail() && ! post_password_required() ) : ?>
						<div class="entry-thumbnail">
							<?php the_post_thumbnail(); ?>
						</div>
						<?php endif; ?>

						<h1 class="entry-title"><?php the_title(); ?></h1>
					</header><!-- .entry-header-full -->

					<div class="entry-content-full">
						<?php the_content(); ?>
						<?php wp_link_pages( array( 'before' => '<div class="page-links"><span class="page-links-title">' . __( 'Pages:', 'twentythirteen' ) . '</span>', 'after' => '</div>', 'link_before' => '<span>', 'link_after' => '</span>' ) ); ?>
					</div><!-- .entry-content-full -->

					<footer class="entry-meta">
						<?php edit_post_link( __( 'Edit', 'twentythirteen' ), '<span class="edit-link">', '</span>' ); ?>
					</footer><!-- .entry-meta-full -->
				</article><!-- #post -->

				<?php comments_template(); ?>
			<?php endwhile; ?>

		</div><!-- #content -->
	</div><!-- #primary -->

<?php get_footer(); ?>
