Parse error referring to an unexpected end of file - css

Question

I was editing the css style sheet on my wordpress website and I got this parse error:
Parse error: syntax error, unexpected end of file in /home/youngt7/public_html/wp-content/themes/young/content.php on line 75
It says it's in the content.php portion, but I am having trouble finding the error. Here is the first lines of my content.php section (sorry it's a little long):
<article id="post-<php the_ID(); ?>" <?php post_class(); ?>
<?php if ( is_sticky() && is_home() && ! is_paged() ) : ?>
<div class="featured-post">
<?php _e( 'Featured post', 'twentytwelve' ); ?>
</div>
<?php endif; ?>
<header class="entry-header">
<?php if ( ! post_password_required() && ! is_attachment() ) :
the_post_thumbnail('thumbnail', array('class' => 'alignleft'));
endif; ?><?php if ( is_search() ) : // Only display Excerpts for Search ?>
<?php if ( is_single() ) : ?>
<h1 class="entry-title"><?php the_title(); ?></h1>
<?php else : ?>
<h1 class="entry-title">
<?php the_title(); ?>
</h1>
<?php endif; // is_single() ?>
<?php if ( comments_open() ) : ?>
<div class="comments-link">
<?php comments_popup_link( '<span class="leave-reply">' . __( 'Leave a reply', 'twentytwelve' ) . '</span>', __( '1 Reply', 'twentytwelve' ), __( '% Replies', 'twentytwelve' ) ); ?>
</div><!-- .comments-link -->
<?php endif; // comments_open() ?>
</header><!-- .entry-header -->
<?php if ( is_search() ) : // Only display Excerpts for Search ?>
<div class="entry-summary">
<?php the_excerpt(); ?>
</div><!-- .entry-summary -->
<?php else : ?>
<div class="entry-content">
<?php the_content( __( 'Continue reading <span class="meta-nav">→</span>', 'twentytwelve' ) ); ?>
<?php wp_link_pages( array( 'before' => '<div class="page-links">' . __( 'Pages:', 'twentytwelve' ), 'after' => '</div>' ) ); ?>
</div><!-- .entry-content -->
<?php endif; ?>
<footer class="entry-meta">
<?php twentytwelve_entry_meta(); ?>
<?php edit_post_link( __( 'Edit', 'twentytwelve' ), '<span class="edit-link">', '</span>' ); ?>
<?php if ( is_singular() && get_the_author_meta( 'description' ) && is_multi_author() ) : // If a user has filled out their description and this is a multi-author blog, show a bio on their entries. ?>
<div class="author-info">
<div class="author-avatar">
<?php
/** This filter is documented in author.php */
$author_bio_avatar_size = apply_filters( 'twentytwelve_author_bio_avatar_size', 68 );
echo get_avatar( get_the_author_meta( 'user_email' ), $author_bio_avatar_size );
?>
</div><!-- .author-avatar -->
<div class="author-description">
<h2><?php printf( __( 'About %s', 'twentytwelve' ), get_the_author() ); ?></h2>
<p><?php the_author_meta( 'description' ); ?></p>
<div class="author-link">
<a href="<?php echo esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ); ?>" rel="author">
<?php printf( __( 'View all posts by %s <span class="meta-nav">→</span>', 'twentytwelve' ), get_the_author() ); ?>
</a>
</div><!-- .author-link -->
</div><!-- .author-description -->
</div><!-- .author-info -->
<?php endif; ?>
</footer><!-- .entry-meta -->
</article><!-- #post -->
That's the entirety of the content.php, any and all help is appreciated. The error is stopping all my content, and I can't access it through the front end until I fix this.
Thanks,
William
p.s. my site is right here if you want to see this from the front end.
