What is Bootstrap?
Basically what is bootstrap? As mentioned in introductory  part this is a front-end framework for making the web pages easier.But how???
As we know , we use CSS classes to make our web page look better and richer. So Bootstrap is nothing but a  set of pre-defined classes which can be used further in our web page to make it better and of course in a fast manner.
What Do I need to install?
As of now you don’t need to install anything on your system use it until you are not experimenting your web page in offline mode.
You just need to include below three lines  in your <  head > tag to ensure the loading of bootstrap libraries to your web page.
