Implementing our introduction section
We will now create an introduction section for our single-page portfolio website. This can be easily modified with the content that your site needs.
The introduction section, as the name suggests, is used to introduce the viewer to the rest of the website. With the use of images and text, the viewer will be able to understand the subject matter of the website.

A jumbotron may sound like a robot from an upcoming Transformers movie, but it is a really cool feature of Bootstrap. Bootstrap borrowed the term from the big displays that are used at sporting events, as it provides a means for prominently displaying information:

A jumbotron in Bootstrap is actually a very simple concept; it is essentially a HTML element used to contain text and images in a large, poster-like fashion.
Unfortunately, our site won't have one of them, but you can add the image into the jumbotron.
