Coraline

A squeaky-clean theme featuring a custom menu, header, background, and layout. Coraline supports 7 widget areas (up to 3 in the sidebar, four in the footer) and featured images (thumbnails for gallery posts and custom header images for posts and pages). It includes styles for print and the Visual Editor, special styles for posts in “Asides” and “Gallery” categories, and has an optional full-width page template that removes the sidebar.

Ari

Ari is a minimalistic, flexible three-column blog theme. The theme uses CSS3 media queries for its responsive layout and is therefore optimized for tablet pcs and smart phones (the theme switches to a two-column layout when viewed on a horizontal iPad screen, and to a one-column layout on iPhones). You can also choose a dark color scheme and the backgound-, text- and link-colors can be customized in the theme options page.

Reddle

Everything about Reddle’s minimal design elegantly adapts to how you want to use your blog and what you want to use it for. Want to use your blog for a simple one-column link blog? A two-column business site with a custom header and no posts? Reddle can do that too — and look good doing it too.

Quintus

A theme that has an old-style appeal with semi-academic graciousness and elegant typography. Fitting for displaying either text or images, Quintus offers a fresh look with room for customization, including custom backgrounds, menus, header images, and the option to publish short aside posts.

Twenty Thirteen
