Answer 1

Include these lines of code in your CSS file
.jumbotron {
margin-bottom: 0px;
}

Answer 2

It is because of:
.jumbotron {
margin-bottom: 2em;
}
So if you want to remove that, simply give a class to your div e.g.: jumbotron-override and add this code to css:
.jumbotron-override {
margin-bottom: 0px;
}
The result can be seen on jsfiddle: https://jsfiddle.net/nabtron/1kesqj8f/4/ (full page: https://fiddle.jshell.net/nabtron/1kesqj8f/4/show/ )
I hope it solves your problem :)

Answer 3

I tried to override your code by commenting margin-bottom: 2rem; then white space disappear
.jumbotron {
/* padding: 2rem 1rem; */
/*margin-bottom: 2rem; */
background-color: #e9ecef;
border-radius: .3rem;
}

Answer 4

I had to put !important after margin: 0px to make it work
.jumbotron {
margin-bottom: 0px!important;
}
