CSS problem

Hey
Everything was working fine but i seem to have done somthing that has made most of the fonts on the main page become small, including the sidebar.
I dont think i edited anything much (though i may have changed some CSS), and also i did use the Adhesive plugin but i disabled it and still have the same problem.
My Index:

<?php get_header(); ?>
<?php
require(“imageRotator.inc.php”);
$rot=new ImageRotator(“images”);

/*
OR
$rot=new ImageRotator;
$rot->setDirectory(“images”);
*/
///Functiuon ImageRotator::getRandomImage() will get the image file name randomly.
?>

<div id=”content” class=”narrowcolumn”>

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?>

<div class=”post”>
<h2 id=”post-<?php the_ID(); ?>”>” rel=”bookmark” title=”Permanent Link to <?php the_title(); ?>”><?php the_title(); ?></h2>
<small><?php the_time(‘F jS, Y’) ?> by <?php the_author() ?>, <?php the_author_description(); ?> </small>

<div class=”entry”>
<?php the_content(‘Read the rest of this entry ???’); ?>
</div>

<p class=”postmetadata”>Posted in <?php the_category(‘, ‘) ?> | <?php edit_post_link(‘Edit’,”,’|‘); ?> <?php comments_popup_link(‘No Comments »’, ‘1 Comment »’, ‘% Comments »’); ?>

<!–
<?php trackback_rdf(); ?>
–>
</div>

<?php endwhile; ?>

<div class=”navigation”>
<div class=”alignleft”><?php posts_nav_link(”,”,’??? Previous Entries’) ?></div>
<div class=”alignright”><?php posts_nav_link(”,’Next Entries ???’,”) ?></div>
</div>

<?php else : ?>

<h2 class=”center”>Not Found</h2>
<p class=”center”><?php _e(“Sorry, but you are looking for something that isn’t here.”); ?>
<?php include (TEMPLATEPATH . “/searchform.php”); ?>

<?php endif; ?>

</div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>
