Gesso is a Sass-based starter theme that outputs accessible HTML5 markup. It uses a mobile-first responsive approach and leverages SMACSS to organize styles as outlined in the Drupal 8 CSS architecture guidelines. This encourages a component-based approach to theming through the creation of discrete, reusable UI elements.

Gesso (pronounced JEH-so) is an art term for the white paint mixture used to prepare a canvas or sculpture for painting. Likewise, the Gesso theme prepares Drupal’s markup and styles to give us a clean starting point.

All development for the Gesso theme is done on Github at github.com/forumone/gesso. There’s also a related Twig-based starterkit for Pattern Lab at github.com/forumone/starterkit-twig-drupal-gesso
