How to make search form full width (resistive)?

Question

css

I use bootstrap and make a search form on the site. I want this for the full width, a large field and a button to find it on the right side of the edge. But I can’t find in the bootstrap documentation in any way that the button does not wrap to a new line when the window is narrowed. It is necessary that the field narrowed, not the button. So that everything is scaled from the phone and not torn.
How can this be done?

Answer 1

well, make a button with an absolute position, or put it in a column and set sizes for all resolutions, well, there col-md-1 col-sm-2 col-xs-3
