In bootstrap, container is
used to set the content’s margin. It contains row elements and the row elements
are container of columns. This is known as grid system.
There are two
container classes in bootstrap:
1.
.container
2.
.container-fluid
Let’s look at each
of the above two class in details with examples:
· .container: The
.container class provides a responsive fixed width container.
In the below
example, the div with class “container” will have a fixed left and right margin
and will not take the complete width of it’s parent or the viewport.

.container-fluid: The .container-fluid class provides a full-width container which spans the
