For this template we used the CSSkel mini-framework, a slim set of rules focused to get all the benefits of the css grid system applied to page diagramation.
CSSkel is a light CSS boilerplate using most updated CSS standards and resources including grids and variables packaged in a light 12k standard css stylesheet.
No need of pre-processors, nor javascripts. Pure CSS to get a basic start your web projects.
It's based on Skeleton and Barebones and inherits their approach to be a lighter css starting point rather han a fully loaded UI framework, ready to start your building process with enought resources to be practical, but also with enought freedom to stop looking like everybody else.
