About This Class

Rapid prototyping is the process of quickly mocking-up early draft versions of a product. A good prototype keeps the complexity out and allows you to receive feedback early on.

In the first part of this class we’ll evaluate the current state of prototyping tools, including wireframing, Samantha Warren’s Style Tiles, Keynotopia, and “sketching with code."

We’ll use Twitter Bootstrap to rapidly develop our own HTML/CSS prototype. We’ll get familiar with the fundamentals, the scaffolding, and other Twitter Bootstrap elements. We’ll also incorporate a variety of external assets for images and typography that will broaden your prototyping toolkit.
