The Tufte-Jekyll theme is a natural extension of the work done by Dave Leipmann on Github after he created a CSS file that allows web writers to use the simple and elegant style employed by Edward Tufte in his published materials. Tufte’s style is known for its extensive use of sidenotes, tight integration of graphics with text, and well-set typography. The idea for this project is essentially cribbed wholesale from Tufte and R Markdown’s Tufte Handout format.
The Jekyll theme adds custom Liquid tags which combine with Github-flavored Markdown and allow an author to write elegant technical work without the need for a lot of hairy HTML.
Fork the repo and put your mad Ruby skillz to work. Some of the liquid tags could be sexed up considerably. For instance, the sidenote tag amped-up with the ability to auto-create numbering would be a huge boon.
