HTML and CSS Reference
In closing out this chapter, let's review what's been discussed so far. CSS3 is not final, but it provides developers
and designers many astounding features to play around with. It also can be used in production campaigns where
performance and ease of use have been discussed, as well as tools that make designing and developing easier. All
of the presentation updates in the submitted spec and working drafts have been reviewed in great detail, and I've
provided code samples you can take advantage of in your next advertising campaign. Last of all, I've covered sprite
sheets, a very important topic—how they're used, what they're used for, and the performance gains that come from
using them, specifically on mobile devices.
Being that optimization is crucial for advertising and for the Web as a whole, I encourage you to take the time to
build these practices into your workflow so that the Web operates faster for everyone. Get excited about using some
of these new features, and be prepared to learn new techniques as they are finalized. CSS3 is no longer solely about
great addition to a designer's tool belt.
