There are two types of layouts available in Bootstrap
Fluid Layout (.container-fluid) : In the Fluid layout, the width is 100 %, this layout changes its width as you are browsing content.
Fixed Layout (.container) : In the Fixed layout, the width is adjusted in pixels, it changes in parts (not continuous), and size will be updated at specified intervals.
Both the layouts are responsive, so any of the above two containers can be chosen to create a responsive design website.
