Intro to Singularity Grid System
Singularity lets you toss out your old, stodgy grid system and it's wacky class names and weird markup requirements. I'll show you how you can use Singularity to create a system of columns and gutters that actually works with your content, allowing different layouts at different media queries, a visual order that isn’t tied to your source order, and works with your own naming convention. Singularity is a Sass plugin which can be used on any Sass project and frees you from needing to use a specific sub-theme for your Drupal site. In fact, it is CMS/theme-agnostic and can be used successfully with many Drupal base themes or even on non-Drupal projects.
