I'm using a Twenty Twelve child theme at http://www.christinabrittain.com/ I've tried multiple things to get my header to fill up the entire container. I've sized it to 1040 instead of 960, but it's still shows as 960. I've changed my header.php to:
<?php $header_image = get_header_image(); if ( ! empty( $header_image ) ) : ?> <a>"><img src="<?php echo esc_url( $header_image ); ?>" class="header-image" width="100%" height="100%" alt="" /></a> <?php endif; ?>

But that doesn't work. Can someone please help?
