我不太理解您的问题,但请尝试以下操作(使用bootstrap v3):
<div class="clearfix">
<?php $a = 0; $classes = array(\'post-1\',\'post-2\',\'post-3\');
query_posts(\'category_name=Menucard\'); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<div class="<?php echo $classes[$a]; ?> col-4 post move pull-left">
<?php
//echo post here
the_content();
?>
</div> <!-- close .post div -->
<?php
$a++; endwhile;
endif;
?>
</div>
