How To Extend Footer 100

How To Extend Footer 100%?

Well I'm totally new to this. Below is my footer, could someone tell me what I need to change/swap to take the footer out of the main body wrapper which currently restricts it to something like 980px. I want to extend the footer 100%. Thanks.

</div>
<!-- END WRAPPER-CONTENT -->

<!-- BEGIN WRAPPER -->
<div id="wrapper-footer">

<div id="footer">

<?php
if (!function_exists('dynamic_sidebar') || !dynamic_sidebar('Footer Widget 1')):
endif;
?>

<?php
if (!function_exists('dynamic_sidebar') || !dynamic_sidebar('Footer Widget 2')):
endif;
?>

<?php
if (!function_exists('dynamic_sidebar') || !dynamic_sidebar('Footer Widget 3')):
endif;
?>

<?php if(get_option('pyre_footer_left') || get_option('pyre_footer_right')): ?>
<div id="footer-bottom">

<?php if(get_option('pyre_footer_left')): ?>
<p class="left"><?php echo get_option('pyre_footer_left'); ?></p>
<?php endif; ?>
<?php if(get_option('pyre_footer_right')): ?>
<p class="right"><?php echo get_option('pyre_footer_right'); ?><a href='#top' class='backToTop'><?php _e('Back to Top', 'Avenue'); ?></a></p>
<?php endif; ?>

</div>
<?php endif; ?>

<!-- END WRAPPER -->

<?php
if(get_option('pyre_analytics')) {
echo get_option('pyre_analytics');
}
?>

<?php wp_footer(); ?>
