Singularity is a next generation grid framework built from the ground up to be responsive. What makes Singularity different? Well, a lot of things. Singularity is based on internal ratios instead of context based which allows for better gutter consistency across breakpoints. Ratio based math also allows for non-uniform grids in any unit you want to use. Layout on the web has changed significantly since Scott's first push back on March 7, 2012. First came Flexbox, then CSS Grid. CSS Grid provides layout functionality that covers all of Singularity's usecases and then quite a few more that we were never really able to support.
