Can you nest Bootstrap containers? - twitter-bootstrap-3

Question

From the docs at http://getbootstrap.com/css/
You may choose one of two containers to use in your projects. Note
that, due to padding and more, neither container is nestable.
and
Turn any fixed-width grid layout into a full-width layout by changing
your outermost .container to .container-fluid.
The second sentence seems to imply that you can have nested containers. The first sentence seems to imply that there should be a single container one a page.
Which is it?
(A case might be wanting to nest a container-fluid inside a container - or simply inside some other element with a fixed width).

Answer 1

You are correct on the ability to use container-fluid
h4 {
margin-top: 25px;
}
.container {
border: solid 5px red;
}
.row {
margin-bottom: 20px;
}
.row .row {
margin-bottom: 0;
}
.nested-container {
border: solid 3px green;
}
.container-fluid {
border: solid 3px blue;
}
[class*="col-"] {
padding-top: 15px;
padding-bottom: 15px;
background-color: #eee;
background-color: rgba(86, 61, 124, .15);
border: 1px solid #ddd;
border: 1px solid rgba(86, 61, 124, .2);
}
hr {
margin-top: 40px;
margin-bottom: 40px;
}
