Hi!
Yep we can do that with css ๐
An example css for this page is
.page-id-436 #promo-bar {
display: none;
}
Now what you want to do is copy paste this code for every page you want to remove it on and replace the ID of the page. For the rackready page, the ID is 436. You can find that ID out either by installing the plugin “show IDs” or similar (http://wordpress.org/plugins/wp-show-ids/ it’s old but maybe it works) and then you can find the ID of every page in the wp-admin > Pages section in order to replace it.
Let me know if that worked out for you ๐
