Blueprint is a CSS framework, which aims to cut down on your CSS development time. It gives you a solid CSS foundation to build your project on top of, with an easy-to-use grid, sensible typography, and even a stylesheet for printing.  

• An easily customizable grid


• Sensible typography


• A baseline (like the background here)


• Perfected CSS reset


• A stylesheet for printing


• No bloat of any kind

I’m going to download it and play with the tutorial. More on this later.
