EXPERTS! Bold preamble in single post

So, why not just type the <strong> tags into the post?

because i have ~8000 posts and post ~10 new each day, what if i 2 months want italic instead, do you think i should edit them all?

well… on your theme’s index page, style the post/content area(div) with bold. Use a different class in single.php.

sorry was unclear, it’s in the single post i want this, to seperate the preamble from the body.

A bit of code (replace <?php the_content(); ?> in a theme’s single.php template with the following):

<?php
$content = explode('<!--more-->', $post->post_content);
if( !empty($content[1]) ) :
?>
<div class="preamble">
<?php echo apply_filters('the_content', $content[0]); ?>
</div>
<?php echo apply_filters('the_content', $content[1]); ?>
<?php else : ?>
<?php the_content(); ?>
<?php endif; ?>

Then just style the teaser text through the .preamble css class.
