Background

Often when working in an online system, you do not have access to edit the CSS itself, but you do have existing libraries within the system that you can draw upon to format your content. Bootstrap is one common library that exists on many web pages.

Task

In JSFiddle or another IDE, create a webpage that uses the Bootstrap library. Place some dummy content in your web page, and modify the HTML to show the following Bootstrap-formatted elements (without adding any CSS):

• A green success button
• A paragraph with a black background and white text
• A red alert message
• A yellow progress bar at 50% completion
• A rounded blockquote element with a shadow

Also be sure that you are using appropriate padding and margins throughout.
