Spacing inline posts

I have a ‘Featured Posts’ section on my homepage, using a loop which pulls three posts from the’Featured’ category and displays them inline.
I want to space out the three posts accross the width of the page.
Here is an image to show what I want

Is there any easy way to do this?
Here is my code for the loop.

<?php $my_query = new WP_Query(‘category_name=Featured&showpost=3’);
while ($my_query->have_posts()): $my_query->the_post();
$thumb = get_post_meta($post->ID, ‘thumb-small’, true);?>
<div class=”feature”>
<*a>”><img src=”<?php echo $thumb; ?>” alt=”<?php the_title() ?>” />
<h2>“><?php the_title() ?></h2>
</div>
<?php endwhile; ?>

So i basically want the first and second posts to have a right margin but not the third, no matter which posts are featured.

Thanks
