I customized TwentyTwelve Theme and change the typography style for my blog, and I’ve submitted this new blog theme to WordPress Theme Directory, now you can download it for free on ThemeVan.com or WordPress.org.
I like minimal & elegant design, get rid of the redundant staff, so I simplify this theme and make it more readable as much as possible. I include two templates for the posts, fullwidth and with right sidebar that you can choose one for your post. Also, you can customize the background and header image as well.
I will keep to update and improve this theme in the future, any suggestions would b eappreciated!
