I'm working on a site using the Coraline theme and I want to place a banner ad above the header. I placed the following code in the header.php after this line of code:
<body <?php body_class(); ?>>
<div class="<?php do_action('container_style'); ?>" id="container">
<div style="background-color: #ffffff">
<img src="http://www.pokerstars.com/bnrs/current/728x90.gif" class="aligncenter">
</div>
<?php do_action('above_header'); ?>
It worked once, but when I refreshed again, the ad disappeared. I had used this on another site before and it had worked, though the theme seemed to be less complicated than the coraline theme. Is there something wrong with the code? Or maybe I placed it in the wrong place?
Any advice would be greatly appreciated. Thanks in advance.
