Featured image appearing below post ?

Sorry about duplicating post i just didnt know where i should have posted my problem.

I added the new Twitter feed recently but I dont understand why if i just change the css ie float the text to the right and create the width to 75% then float my image to the left why that should effect my header

I have add it to a hook in the functions.php file so i cant “deactivate” however looking over the code if seem it be ok

<?php
}

add_action('thematic_header', 'toptwitter', 5);
function toptwitter(){ ?>
      <div class='twitter' id='toptwitter'>
       <h3><a href='http://www.twitter.com/sligotourism' target='_blank'>Sligo Tweets</a></h3>
        <ul id='twitter_update_list'>
        <li><?php echo do_shortcode( "[rotatingtweets screen_name='sligotourism' include_rts = '0' tweet_count='5' timeout='9000' get_favorites = '0' rotation_type ='scrollRight' show_meta_timestamp = '0' show_meta_screen_name = '0' show_meta_via = '0' show_meta_reply_retweet_favorite = '0'  links_in_new_window = '1' ]" ) ?>
</li></ul>
      </div>
<?php
}

So i am not so sure thats the problem.

However looking at the source code I see the div that is holding the text is above the div holding the image

I figured it out. While looking at the css file I removed a comma
