* Do not put `.jumbotron` inside `.container` or `.container-fluid`. Instead, close the container before adding Jumbotron to the page, then follow it by opening a new container afterward if necessary.
* You can use the `.jumbotron` and `.hero` classes interchangably. Microsoft sites call this component _Hero_ which is why the class is offered here.
* Add theme classes `.theme-default`, `.theme-light`, `.theme-dark`, and `.theme-alt` at the `.jumbotron` level.
* Each theme class has default background-colors because Bootsrap explicitly sets background color for `.jumbotron`.
