The current site style is built on Pure, a small set of responsive CSS modules from Yahoo. In this setting, "responsive" means that the site should adapt gracefully to different screen sizes and window sizes. The new design hues closely to Pure's side menu layout example, and I have in no way modified the default CSS behavior from the Pure framework.
For content management, I am using Jekyll 2.4.0 a plain-text static site generator. Jekyll may be the most popular of the available static site generators, in part because it is used in Github Pages. The chief goal of using Jekyll is to separate the content from presentation, making it simpler to apply general stylistic changes in the future.
