You’ll learn to work with .info and tpl.php template files, how to add CSS and JavaScript, how to work with the render system new in Drupal 7, how to override templates, create regions, and use the Theme Developer tool.
You’ll start with the original HTML, CSS and JavaScript template files that were provided by the designer so that you can follow along in translating the design into a Drupal 7 theme. The video explains Drupal’s design vernacular, concepts, and special needs. We’ll show you how to associate the proper CSS & Javascript files, add all of the necessary regions, and control the HTML output through page and node-specific templates. You’ll learn about the best tools and strategies for controlling the look and feel of your Drupal website.
This video series will cover the basics of Drupal theming while the more advanced theming topics of working with the template.php file will be covered in the Advanced Theming video series.
