I gave a talk at FITC Web Unleashed 2014 on Twitter Bootstrap.
Twitter Bootstrap is a wildly popular HTML and CSS framework for building websites and web applications. It is the number 1 project on GitHub. Bootstrap supports responsive web design, allowing the layout of your page to adapt to the device (desktop, tablet, mobile). This talk will introduce you to the basics of using Bootstrap and show you how to build responsive web layouts to build your own app.
