The goal of this session is to explore OSS (open source software) themes, both core and contributed, to find useful techniques and snippets of code that help speed up theme development or upgrade older themes.
Projects we might explore include 4Kitchens Emulsify, DrupalX, Wingsuit, Olivero, Rain, DrupalGovCon2017 theme, and more.
If you are new to Drupal or haven't done much theming this session should glance at what's available and how you could leverage those to build or upgrade your theme.
