How do I get rid of the division in my content.php

Hi,

I want my text to be in line with the thumbnails on posts on my site. I’m guessing I need to somehow change this code, but don’t know how:

<p style="float:right"><?php if(is_single() || is_page())
if ( has_post_thumbnail() ) {
the_post_thumbnail('medium');
}
echo '<hr class="featurette-divider">';
?></p>

Suggestions…?

Thanks,

Lia
