Urgent help!! styling posts

i have a problem with the style of a post
i want to make the thumbnails to the left and the content to the right withouth having the text going under the image, but cant manage to put the divs in a right manner to do that. I am using this code to call the post from a certain category:

<?php the_ttftext("Calendario"); ?>
<h2>Entorno Cafetto</h2>
<?php $recent = new WP_Query(); ?>
<?php $recent->query('cat=6&showposts=50'); ?>
<?php while($recent->have_posts()) : $recent->the_post(); ?>

<?php the_post_thumbnail(array( 120,120 )); ?>
<div class="calendario">

         <h4> <?php the_title(); ?></h4>

<?php the_content('more_link_text', strip_teaser, 'more_file'); ?><?php endwhile; ?>

</div>

and the css related to it:

.wp-post-image  {
float: left;
border: 5px solid white;
display:block;
clear:left;
}

.calendario {
display:block;
clear:left;
float:left;
}
