Drupal 8 has a new theme layer. A new theme engine named Twig has been introduced already, and the rest of the system is also getting an overhaul.
By refactoring the HTML and CSS that comes out of core, and translating all our PHPTtemplate files and theme functions into Twig templates, we think we'll be able to create a Drupal Theming wonderland where things are consistent, intuitive, and easy to work with.
In this session We'll point out some of the problems we faced with PHPTemplate and Renderables, and show how these tissues are being addressed through the move to Twig. There's still a lot to do, and some things we haven't decided on yet, but we're making progress.
Come see what your new template files will look like, and learn how you can get involved in making a better Tommorrow for your favorite CMS.
