styling custom page template fot twenty thirteen

Hello,

I am using this code for a custom page template on a twenty thirteen child theme. The template is working, and the slider is working, but no matter what I have tried I am unable to style slider-wrap or home-slider. Any ideas what I need to add to my style.css??

get_header(); ?>

			<div class="slider-wrap">
			    <div id="home-slider">

			    <?php nivo_slider('landscape'); ?>

		    	</div>
		    </div> 

     <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">
						<?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 -->

					<div class="entry-content">
						<?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 -->

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

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

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

<?php get_footer(); ?>
