Variables
The variables available define both breakpoints and colors. Currently there are 4 breakpoint variables based on various device sizes that are being targeted. You can take a look at the breakpoint mixin to see where you might use them. The color variables have a new take on what color definitions should look like.
The colors offered are listed in terms of weights instead of shades. If you think about the number following a color variable in the same way that you would think of a font-weight, then each variable “weight” will match that of another color. It’s an easy way to determine what colors to use and what colors will go well together.
