rand posts from each category

Wanting to display one random posts from each category on my home page, below is what I have but I get the feeling it could be improved. Is there a way to make this into one loop that encompasses all categories?

Another thing is I cant seem to get it to line up horizontaly, it seems to stagger on top of each other, also pasted my css for that div class.

<!--archivos aleatorios-->
<div class="rand-posts">
    <?php
$args = array( 'numberposts' => 1, 'category' => '1' , 'orderby' => 'rand' );
$rand_posts = get_posts( $args );
foreach( $rand_posts as $post ) : ?>
	<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?><br /></a>Editorial / <?php the_title(); ?>
<?php endforeach; ?>

    <?php
$args = array( 'numberposts' => 1, 'category' => '3' , 'orderby' => 'rand' );
$rand_posts = get_posts( $args );
foreach( $rand_posts as $post ) : ?>
	<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?><br /></a>Retratos / <?php the_title(); ?>
<?php endforeach; ?>

    <?php
$args = array( 'numberposts' => 1, 'category' => '4' , 'orderby' => 'rand' );
$rand_posts = get_posts( $args );
foreach( $rand_posts as $post ) : ?>
	<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?><br /></a>Comida / <?php the_title(); ?>
<?php endforeach; ?>

    <?php
$args = array( 'numberposts' => 1, 'category' => '5' , 'orderby' => 'rand' );
$rand_posts = get_posts( $args );
foreach( $rand_posts as $post ) : ?>
	<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?><br /></a>Personal / <?php the_title(); ?>
<?php endforeach; ?>

<br /></div>

The div class rand-posts

.rand-posts {
	width: 200px;
	margin: 0;
	padding: 0;
	float: left;
	clear: none;
}
