Themes allow you to change the look and feel of your Drupal site. You can use themes contributed by others or create your own to share with the community. Contributed themes are not part of any official release and may not have optimized code/functionality for your purposes.
You can also create a sub-theme of an existing theme. A sub-theme inherits a parent theme's resources. Read more about Sub-theme structure and inheritance.
You can also view a full index of themes listing only their titles.
Bear Skin is the default theme for the Bear starter profile, which is a profile to use as a starter kit when building a new site. Bear Skin does not rely on the profile, but can be used as a simple, clean theme. Bear Skin is somewhere between a pure starter theme and a more styled theme. It can be used as a starter theme that will be heavily customized, or, for smaller projects, it can be lightly customized and give you a nice looking responsive theme with little work.
Gratis is a modern, flat design, and responsive Drupal 7 theme. It's developed and designed by Danny Englander (@Danny_Englander).
Gratis 2 / LibSass version / demo
Gratis 2 for Drupal 7 incorporates LibSass, Bourbon, Susy, and Grunt. Gratis is somewhat the antithesis of frameworks like Zurb Foundation and Bootstrap. It's minimalistic with no rigid grid classes. Over time Gratis has evolved to be a little more esoteric. Full sub-theming is now supported and a starter kit comes with the theme.
Gratis is aimed at users who want to get a nice looking theme up and running in short order, but may not want to take the time to create a sub-theme and fiddle with regions, settings, media queries, and other highly technical things. It's also aimed at a casual Drupal user who has some familiarity with building sites. This theme also does not require any base theme.
Beep Edition is designed from the ground up as a mobile-first responsive theme. I created this out of the desire to make as light-weight a theme as I could, using all the tricks I know to make it a solid HTML5/CSS3 responsibly-responsive starting point. It does use SASS/Compass and Zen Grids (minimal use of grids to be honest), and has icon fonts from Font Awesome included. What might be of greatest interest is that I've added an off-canvas menu solution that works 'out of the box' with nice menus, without having to resort to any showing/hiding of extra 'stuff'.
This is admittedly pretty rough, but I think it's a good starting point and lighter in code and 'stuff' than anything else I've tried. It's been a good starting point for many projects now, and is based upon what I learned creating a responsive Zen starter theme in D6 that I've shared with many people over the past few years.
I'm looking forward to collaborating with others on this - I'd like to develop this further with everyone's contributions. I don't want it to be an all-consuming everything theme - but I do want it to continue to serve as a solid starting point (and one that I use for rapid prototyping and 'living wireframing' with clients) for projects that can go pretty much anywhere.
