Ultima is an advanced, blank HTML5 starter theme with robust structure.
Unlike most other starter themes, Ultima is a standalone theme which does not get into your way. This makes it suitable for any custom design and project of any complexity. Think of it as Drupal version of Underscores theme for WordPress.
Ultima is opinionated only when it comes to the file and folder structure. The template.php file is used for including all other function files in the theme, keeping the code well organized and avoiding 1k+ lines long files with functions and overrides.
It is not coming with any existing CSS frameworks or styles. Everything is left up to the designer and the specifics of a project.
Features:
Default implementations of most preprocess hooks (html, node, page etc.)
Form alter implementation
Extended body classes
Adding vocabulary ID
Adding all parts of the current URL; for example: url-user url-user-login
Adding all roles of the current user; example: user-role-authenticated user-role-administrator
Separate templates for full and listing (teaser) node views
Adding page titles to user login, registration and password reset pages
Minimalism is an HTML5 and CSS3 template that is minimal and beautiful in its simplicity. Combines multiple-column groupings and newspaper style column.
