The Plain v2
A minimalist Jekyll theme that focuses on writing matters, made with passion for simplicity. A great, white clean theme for personal blog use. Made with Sass which automates the compression of the compiled CSS code, and cool Jekyll layout by Anatol Broder for compressing the HTML code on-the-fly. Typeface used is Karla from Google Fonts.

This theme is based on Leonard Lamprecht's original Jekyll theme.
