While the first three volumes of this series focused on colors, basic design elements, and web design technologies, Volume 4 focuses on portfolio sites, covering styles and trends, and organizing these portfolio sites by region, agency size, and type of work. In addition to this in-depth look at portfolio sites, you’ll also find examples and explanations of design styles and themes, as well as design and responsive elements.
