What is Bootstrap and Basic Structure of Bootstrap

Bootstrap is an open source project originally created by Twitter to enable creation of responsive, mobile first web pages. Bootstrap has a standard set of classes that allow developers to quickly create applications that scale to devices of all sizes, and incorporate common components such as dialog boxes and validation. Bootstrap has become a defacto standard for web design.

So why should you choose Bootstrap? Here are 6 great reasons:

Reason #1. Easy to get started.

Reason #2. Great grid system.

Reason #3. Base styling for most HTML elements.

Reason #4. Extensive list of components.

Reason #5. Bundled Javascript plugins.

Reason #6. Good documentation.
