Features

• Unlimited nesting with consistently sized gutters.
• Nesting without parent contexts. For instance in Jeet you have to write column(1/3 1/2) where 1/2 is the size of the containing element. All ratio grid systems aside from Elf suffer from this in some form or fashion.
• Ratio based sizing (e.g. column(1/3).
• Gutters can be any unit (e.g. 30px, 2rem, etc.). These are static so you can space elements vertically as well for a perfect grid.
• Tiny file size compared to other ratio grid systems.
• Flexbox makes short work of aligning elements vertically and horizontally.
