About the @grid-float-breakpoint variable in BS 3

Question

In Boostrap 3 documentation I have found this:

Customize the collapsing point

Depending on the content in your navbar, you might need to change the point at which your navbar switches between collapsed and horizontal mode. Customize the @grid-float-breakpoint variable or add your own media query.

Could I define the @grid-float-breakpoint variable in a main.css file or should I generate a new customized boostrap obligatory?

Answer 1

@grid-float-breakpoint is a LESS variable, you can't use it in plain CSS nor in SASS. Change the value in customizer, then download your new build.
