Drupal 7 Theming Cookbook

Overview of this book

<p>The greatest strength of Drupal lies in its design which, when employed correctly, allows developers to literally handcraft every aspect of a site, so that it looks and performs exactly how they want it to. While it is reasonably straightforward to download a Drupal theme and install it, doing anything beyond that is not. Using custom themes requires familiarity and experience with Drupal's theming system, especially if you want to easily administer and maintain your themes.</p> <p>Drupal 7 Theming Cookbook provides a plethora of recipes that enable Drupal template designers to make full use of its extensibility and style their site just the way they want it. It is a well-rounded guide which will allow users to take full advantage of Drupal's theming system.</p> <p>This cookbook starts with recipes which address the basics of Drupal's theme system, including regions and blocks. It then moves on to advanced topics such as creating a custom theme and using it to modify the layout and style of content. With the introduction of the Field API and the growing importance of Views and Panels in Drupal 7, chapters have been dedicated to each feature. You will also learn many techniques for dealing with Drupal&rsquo;s templating system, which will allow you create themes which surpass even the existing Drupal and contributed modules.</p>

Thankfully, however, things have changed considerably since then. Browsers have evolved and standards have improved. JavaScript is now a potent weapon in any themer's armory and this is especially true with the introduction of cross-browser libraries and frameworks which address most of the aforementioned issues with it.

JavaScript libraries take out the majority of the hassle involved...
