By following this guide I was able to clone(almost) the default htm5 template. But like what others have noticed, some functionalities are missing. Still I think this is quite promising since developers are welcome to share. I wish we can edit blocks to include the accompanying CSS and be able to see the block itself interactively.

I've tried to install on localhost but twice failed due to deprecated mysql functions. I'm using MySql v5.6. Looks like it needs to be updated to conform to MySql 5.5 and above.
