In this chapter, we've learned how to easily select almost anything we need on the page with CSS3's new selectors. We've also looked at how we can make responsive columns for content in record time and solve common and annoying problems such as long URL wrapping. We now also have an understanding of CSS3's new color module and how we can apply colors with RGB and HSL complete with transparent alpha layers for great aesthetic effects. In this chapter, we've also learned how to add custom fonts to a design with the @font-face rule, finally freeing us from the shackles of the humdrum selection of "web-safe" fonts we're used to designing with. Despite all these great new features and techniques, we've only picked at the surface of what we can do with CSS3. Let's move on now and look at even more ways CSS3 can make a responsive design as fast, efficient, and maintainable as possible with CSS3 text shadows, box shadows, gradients, and multiple backgrounds.
