Theme development

I've created an additional CSS theme for the sub module while the primary front-end dev is working on style.css.

Hi,

I've just taken over a site that has the Max theme (Drupal 7), and want to add an announcement banner to the top of the page (just some HTML and CSS).

I've tried declaring a new region in the Max.info file, editing the html.tpl.php file, and creating a region--banner.tpl.php file in the templates folder - all to no avail.

I've not worked with Drupal before and am unclear on regions, modules, zones, etc. If someone could let me know how I can achieve this/point me in the right direction, that would be great!

Thanks in advance.
