The Apathy theme is a crisp, universal three-column dynamic layout that is extremely lightweight and casual. The theme emulates a digital version of the traditional newsprint format, and validates as XHTML strict. Although the CSS only approaches valid, Apathy appears virtually identical on all modern browsers. If you are focusing on text-based content and strive toward coherent, concise presentation, the Apathy theme will serve you well..
