Our default Jekyll templates are themed by two Sass files found in the /_scss folder of your project repo; theme.scss and bowtie.scss. The quickest way to theme one of our templates is to update the variables in theme.scss. Read this post on how to update your theme for more information.
The BowTie templates and themes are meant as a learning resource. You can view the source on our github page.
