10. Bootstrap 3
“With Bootstrap 2, we added optional mobile
friendly styles for key aspects of the framework.
With Bootstrap 3, we've rewritten the project to be
mobile friendly from the start. Instead of adding on
optional mobile styles, they're baked right into the
core. In fact, Bootstrap is mobile first. Mobile first
styles can be found throughout the entire library
instead of in separate files.”
