Bootstrap 4 Components
Jumbotron
Jumbotron is the large callout in a website that gathers much attention. To create a jumbotron use the class .jumbotron inside the <div> element. Place this within a .container class. By default, BootStrap jumbotron is light gray in color which, of course, can be changed.
To add jumbotron that extends the entire viewport of the browser and without the round edges add .jumbotron-fluidutility class and place the container class within the jumbotron.
