Re: How to add different style to the first post?
That is the right thing to edit! One way to do it is to add a counter
<?php
$postorder = 0;
foreach ($posts as $bb_post) : $del_class = post_del_class(); ?>
<?php $postorder++;
<li id="post-<?php post_id(); ?>" class="entry-<?php echo $postorder; ?>"<?php alt_class('post', $del_class); ?>>
<?php bb_post_template(); ?>
</li>
<?php endforeach; ?>
Then you can just use CSS and format li.entry-1
however you like!
