Several CSS code examples showing off what CSS can do in 2019 when it comes to art direction, including typography, images, and more. Clarke especially brings forth the excitement of grid and flexbox, which are big improvements for layout, moving away from floats and tables. This whole book even brands itself throughout each chapter, giving its own example of art direction.
I struggled a bit at the beginning of the book because I develop and design for government sites, and his examples seem best for news outlets and advertising. However, once I hit a lot of practical advice and code examples, I couldn't put it down. I learned several new tricks myself, and have ideas for the more creative parts of the government sites I manage.
2019 is, indeed, an exciting time to be designing websites!
As an added note, I jumped between hardcover and ebook. Ebook was more readable for me, personally, but the hardcover is beautiful to look through.
