Multi row post list

Ended up with using this code:

<?php query_posts('category_name=Menucard'); ?>
    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

    <div class="span4 post move pull-left">
        <?php
            //echo post here
            the_content();
        ?>

    </div> <!-- close .post div -->

    <?php
        $counter++;
        if ($counter % 3 == 0) {
        echo '<div style="clear:both;"></div>';
        }
    ?>
