Making it look good – using Twitter bootstrap

In the interest of saving time and focus more on code, we will "outsource" the design in this book and layout to Twitter bootstrap (which you can access at http://getbootstrap.com). Bootstrap defines a grid system that governs all layouts and it also has well-defined CSS to make things look good. It comes with a predefined theme that looks great, and there are other themes out there if you want to change the themes.
