It’s already 2016 and I’m hard at work on my latest project to help you learn Cool CSS. But while that book isn’t out yet, you can check out some of my work in the form of free chapters and free videos.
Free Responsive Web Design and Bootstrap Chapters
You can get started quickly with Bootstrap with the free chapter: Build Your First Bootstrap Website with the Basic Template from my book Teach Yourself Bootstrap.
I also released a video course last year: Learning HTML and CSS LiveLessons, and there are two free videos available on InformIT to help you get started learning HTML and CSS.
