This project has been dormant for some time and new installs and upgrades should seriously consider a more robust and actively-maintained grid-compatible base theme, like Omega.
Panels 960gs extends Boron, another minimal base theme which converts the core template files to HTML5 markup.
How To Install
- Install Boron
- Install Ctools and Panels
- Install & enable Panels 960gs
- Get yourself a nice admin theme like Rubik (you'll need its base theme Tao as well)
- Cleanup: Go to [yoursite.com]/admin/structure/block and disable all blocks in the Content region except "Main page content".
- Enjoy, and don't forget to report bugs or give feedback to better this theme.
