We’ve spent the first two chapters in training, getting up to speed with what’s currently usable today in terms of CSS3. We also talked about how the experience layer is currently the most appropriate place to apply that usable CSS3.

To recap the important bits we’ve covered so far, let’s keep in mind that:

1. There are core CSS3 properties that are usable today.
2. Everyone can use these core properties in their own projects, especially when targeted at the experience layer.
3. Vendor prefixes allow us to push forward right now, helping test in-flux properties in real-world contexts.
4. CSS Transitions are no longer proprietary experiments, but draft specifications that other browsers are embracing. Let’s use ’em!
