SirBones is the basic of basic themes. It has the most barebones possible without not even having a theme at all!
A few commonly asked questions.
Is SirBones HTML5?
It certainly is my fellow friend!
Can SirBones map my something to my funny widget?
No... Let me repeat, SirBones is nothing more then a HTML 5 starter. It includes ZERO functionality to make things happen (like other themes such as Zen, Omega, etc do).
Is SirBones responsive?
If you make it responsive it is. It's literally nothing more then a HTML file and a few lines of CSS.
