Minnow is designed as a utility framework with just the bare essentials. The minified file size of the core is extra small due to these principals.
Grid columns, font sizes, padding, margins all use rem units as the standard. Pixel fallbacks are included by default but can easily be disabled.
Minnow is assembled with the beautifully powerful Sass (.scss) syntax. Minnow uses several mixins and variables to make extending on the core a breeze.
A feature-packed SCSS variable file that can be used for making global changes at a rapid pace.
