Thematic is a pretty cool theme development framework for WordPress although I believe it can be improved.
One great thing about thematic is the ability to create css based on the template file.
For example, the single.php template will include the css class ’single’ in the body classes of the html:
<body class="... ... single ...">
The dog-page-template.php, a custom page template will include:
<body class="... ... dog-page-template ...">
So if you want to customize any links for those specific pages you simply place:
body.single a {}
body.dog-page-template a {}
