Solved most of the style sheet issues except these:
There's an outside border around all the search and results forms, but can't seem to find a style sheet for it.
Trying to add an underscore between search results items in a Prod_results.php page. Adding via the 'body,td,th' rule adds an underscore not only to the search results, but also to other cells as well. Everything I've tried either adds the underscore to all cells on the page or only to certain WA dynamic cells in each row of the table. The WADATableCell rule works fine on 'news_results.php', but adds underscores to every cell on the page on 'Prod_results.php'
Lastly, the style Compact_Default works differently on each of the two pages. Prod_results.php is indented properly, while news_results.php is not.
