Class for the_content

Hello,

I’ve started making my own theme for my website, but now I ran into a problem. Everything worked out fine except for the the_content(”) part. Somehow the class it’s supposed to have doesn’t apply to it, here’s my code:

<?php

get_header(); ?>

        <div class="clear"></div>
      <div id="content-left">
       	  <h1>Professional Design</h1>

	<?php if (have_posts()) : ?>

		<?php while (have_posts()) : the_post(); ?>

            <img src="wp-content/themes/robindebije/images/temp-thumb.gif" width="189" class="news-img" />

        <div class="news-container-right"  id="post-<?php the_ID(); ?>">
            	<p class="news-title"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
          <p class="author"><?php the_author() ?></p>
                <p class="date"><?php the_time('F jS, Y') ?></p>

<p class="news-content">
<?php the_content(''); ?>
</p>

				<p class="view-full-article"><a href="<?php the_permalink() ?>">View full article</a></p>
                <p class="view-comments"><?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?></p>
        </div>
            <div class="clear"></div>

		<?php endwhile; ?>

			<p class="older-or-newer"><?php next_posts_link('&laquo; Older Entries') ?></p>
			<p class="older-or-newer"><?php previous_posts_link('Newer Entries &raquo;') ?></p>

	<?php else : ?>

		<h2 class="center">Not Found</h2>
		<p class="center">Sorry, but you are looking for something that isn't here.</p>
		<?php get_search_form(); ?>

	<?php endif; ?>
      </div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>

This is the part it’s all about

<p class="news-content">
<?php the_content(''); ?>
</p>

When I view my site the content doesn’t seem to use any CSS of the news-content class, which it should.
Hope you can help me, first time I make a theme 🙂
