Bootstrap 3.0.0 - what is replacement of bootstrap-responsive.css?

Question

After I upgraded my application to bootstrap 3.0.0 from bootstrap 2.3.2 it doesn\'t layout very well, and it seems to be because of missing bootstrap-responsive.css in this

Answer 1

In Bootstrap 3.0 there is not needed resposive css. Quoting migration guide:

"Mobile first" is a responsive Web design practice that prioritizes consideration of smart phones and mobile devices when creating Web pages. For Bootstrap 3, there is no longer a separate bootstrap-responsive.css file. All responsive features are now compiled into a single core bootstrap.css file.
