Align Caption to Right – Content Slider Plugin

I’m using the WordPress Content Slide Plugin and wondering how I can make the caption align to the right instead of the bottom.

I’m able to figure it out using firebug on the actual page but when I mess with the code in the plugin editor I’m not getting the results I want.

I would also like to try and add a “read more” link at the end of the caption but it’s not showing up at all. This is the code I put in:
<a href="<?php the_permalink(); ?>">read more</a>

and this is where I’m editing within the content-slide/content_slide.php file:

<?php if($wpcs_settings['show_excerpt'] == 'true') { ?>
            <span><h4><?php the_title(); ?></h4><p class="excerpt"><?php the_excerpt(); ?><a href="<?php the_permalink(); ?>">read more</a></p></span>
        <?php } ?>

Any help would be greatly appreciated. Thanks!
