Is there a validator for Bootstrap HTML?

There is no "is there a Javascript form validator that works with Bootstrap", but "is there a validator that looks at your code and marks issues that match Bootstrap itself" - eg

• Number of columns
• with more than 12 added, which would be an error
• outside of the container, which would be a warning because you may have done this on purpose, but somewhat unusual

I think this would be a good idea, especially since I find myself getting into very complex nested Bootstrap layouts.
