wordpress show posts loop with feature image thumbnail

PHP

<?php /* Template Name: Blog Posts */ get_header(); ?>

<?php 
$args = array( 'posts_per_page' => '10' );
$recent_posts = new WP_Query($args);
while( $recent_posts->have_posts() ) :  
    $recent_posts->the_post() ?>
    <div class='post-list-item'>
        <a href="<?php echo get_permalink() ?>"><?php the_title() ?></a> 
        <?php if ( has_post_thumbnail() ) : ?>
            <?php the_post_thumbnail('thumbnail') ?>
        <?php endif ?>
		<?php the_excerpt(); ?>
    </div>
<?php endwhile; ?>
<?php wp_reset_postdata();?> 

<?php get_sidebar(); ?>

<?php get_footer(); ?>
here is another version of this, using foundation for the row and grid items to make it work nicer on responsive

<?php /* Template Name: Blog Posts */ get_header(); ?>

<div class='row'> 
<div class='large-12 columns'>

<?php 
$args = array( 'posts_per_page' => '10' );
$recent_posts = new WP_Query($args);
while( $recent_posts->have_posts() ) :  
    $recent_posts->the_post() ?>

<div class='row'>
    <div class='medium-2 columns'>
        <?php if ( has_post_thumbnail() ) : ?>
            <?php the_post_thumbnail('thumbnail') ?>
        <?php endif ?>
	</div>
    <div class='medium-10 columns'>
        <a href="<?php echo get_permalink() ?>"><?php the_title() ?></a> 

		<?php the_excerpt(); ?>
	</div>
</div>

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

</div>
</div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>
