Bootstrap: Jumbotron & Forms

If you want to make your message outstanding on the web page, Jumbotron can be a good style choice. Jumbotron is a lightweight, flexible component that can optionally extend the entire viewport to showcase key content on your site. (From Bootstrap Components-Jumbotron)

The final page looks like:
