This theme is a good match for a small to medium scale online magazine or news site. It has a menu that is easy to navigate, a two-column layout for content, easy to access archive pages. It also features a bit different single post design layout with a tightly integrated related posts section that might be effective and improve reader engagement compared to the standard WordPress single post design.
Rowling theme was built with mobile users in mind. The layout is 100% responsive, so the content looks crisp and clear on every single device, no matter what resolution it is viewed on. This theme combines a few commonly used Google fonts that look great together. The serif fonts give that editorial vibe to the theme, making it easy to read.
If you like making customizations to the theme, there are some options available, including custom logo support, the choice of custom accent color, three different menu areas and a few custom widgets. That doesn't seem like much, but you can always do some extra to the code or install a few additional plugins.
