 Need a grid without the gutters? For instance, for a horizontal navigation where you want buttons touching. Do so with `span(1/5)`. No need to pass more than one ratio since we don't need to worry about the math involved with gutters and all that.

 When assigning multiple ratio contexts to a `col()`, do you want to reference the outer most container first? Example: Let's assume we have a column set to `col(1/4)` that is nested inside of another column that is `col(1/3)` which is nested inside of another column that is `col(1/2)`. By default, to maintain consistently sized gutters (even when nesting), our inner-most column would look like `col(1/4 1/3 1/2)`. If we adjust this global variable to be `true`, our inner-most column could be written from a top-down perspective like so: `col(1/2 1/3 1/4)`. This is entirely a preference thing. Do you like stepping up or down?
 
+### nth: "child"
+
+Switches between using `nth-child` or `nth-of-type` when rendering grid classes. The default is
+`nth-child`. Use `"type"` if you wish to use `nth-of-type`.
