riancallahan_com_neato is a subtheme of the Neato theme for Drupal 8. Neato is based on the Bourbon Neat responsive grid framework. This subtheme uses media queries, preprocess functions, and Gulp + Bower + NPM.
All SASS code is organized using a SMACSS approach. Modified Twig templates are used to simplify both HTML structure and default class-naming logic. Extra fields have been added to the theme's Settings page for use in twig templates.
