What is jumbotron?
A jumbotorn indicates a big box  for calling extra attention to some special content or information. A jumbotron is displayed as a
grey box with rounded corner . It also enlarges the font sizes of the text inside it
As the name suggest this component can optionally increases the size of headings and add a lot of margin for landing page content.

To use the Jumbotron:
? simply create a container <div> with the class of .jumbotron.
? In addition to a larger <h1>, the font-weight is reduced to 200px.


The following example demonstrates this:

<div class="container"> <div class="jumbotron"> <h1>Welcome to landing page!</h1>
<p>This is an example for jumbotron.</p>
<p><a class="btn btn-primary btn-lg" role="button"> Learn more</a> </p>
</div> </div>

  

To get a jumbotron full width, and without rounded corners use the .jumbotron class outside all.container classes and instead add a .container within as shown
in the following example:

<div class="jumbotron"> <div class="container"> <h1>Welcome to landing page!</h1>
<p>This is an example for jumbotron.</p> <p><a class="btn btn-primary btn-lg" role="button"> Learn more</a> </p>
</div>
</div>
