[WORDPRESS] How to apply Different Style for Different Posts in a Loop ?

Hello everyone. I need a small help with wordpress and php codes. I
have a featured posts slider on my homepage and here is the code for
it -

<?php
            $getcat = get_option('dynata_slider_category');
            if($getcat=="all" || $getcat=="All Categories"){ $querycat = ""; }
            else{ $querycat = "&category_name=" . $getcat; }
            ?>
            <ul>
                <?php query_posts("showposts=3" . $querycat);?>
                <?php while (have_posts()) : the_post(); ?>    
                    <li>
                    <?php if(get_post_custom_values("feature")){ ?>
                    <img src="/wp-content/uploads<?php $values =
get_post_custom_values("feature"); echo $values[0]; ?>" alt="<?php
the_title(); ?>"/>
                    <div><a href="<?php the_permalink() ?>"  title="Permanent Link to
<?php the_title_attribute(); ?>">Read Full Article</a></div>
                    <div><?php the_title_attribute(); ?>"</div>
                    <?php } ?>
                    </li>
                  <?php endwhile; ?>

Code (markup):

but the problem is that in this loop, every post and its image appear at the same position as a slideshow.
BUT What When I Want To Display Each Post With Different Style ? Like i want the featured posts to appear in 3 boxes. They all are not at the same place, so they each have different DIV style (position, padding, margin, left, right, z-index all are different for different box)
So how do i add different DIV style in that code ?

 

You have to write here full code. This part is not enough to help you.

 

what more do i need ? that part of code is enough i think because its the part where i am having problem. you don't need anything else in a wordpress file to show posts

 

OK, I will predict!!! I think you have to change the div id and add different ids for each post.

 

hmmm ok i did it myself by adding a variable in the while loop which increases on every loop and used it in the div.
By the way, Thanks s_ruben for sparing your time
