[Giovanny]

How can I align my WordPress footer text.

here's the code:

</div><!-- /marginauto -->

<div class="footer">
<div class="marginauto">
<?php ?>

<?php _e('Copyright 2011 WORDPRESS.com ', 'blank') ?>


<br />
</div>
</div>

<div><?php wp_footer();?></div>
<script type="text/javascript"> Cufon.now(); </script>

</body>
</html>

How can I align-center "WORDPRESS.com" to my blog.
