Why is the .inline class more efficient?
Just struggling to understand why the inline class is created for the responsive buttons... Why didn't Guil just reuse the .btn class and set the display value to inline-block when the viewport is at 769px or greater?

I think just to make sure that classes are not reused and to make it as DRY as possible which is after all what the video is about. With an extra class and assigning the class to the media query that makes sure that single style rule is used only for the media query rather than reusing a selector and changing it's style.
There's also a login button that he doesn't want to target with the media query :0)
