Immutable margin and padding utilities are based on a global white space scale defined with custom properties. These can dramatically help reduce the size of large stylesheets and allow for greater flexibility and quicker iteration when designing in the browser.
Due to the ubiquitous nature of setting margin and padding, these utilities use a shorthand naming convention.
|x||X-axis (left and right)|
|y||Y-axis (top and bottom)|
|n||Negative (margin only)|
|1||--space-1 (default .5rem)|
|2||--space-2 (default 1rem)|
|3||--space-3 (default 2rem)|
|4||--space-4 (default 4rem)|
Change or reset default margins using the white space scale. Negative x-axis margins are used to offset margins and padding of child elements. Margin auto is used to horizontally center block-level elements with a set width.
Padding utilities are only available in symmetrical orientations. This is to normalize the spacing used around elements and maintain a consistent visual rhythm.
To increase information density and to better align elements, remove default margins from typographic elements using the margin utilities.

The negative margin utilities also work with padded children.

Margins and padding should never be declared outside of these utilities. This is meant to help create consistency and avoid magic numbers. If, for some reason, the default white space scale does not suit your design, customize and extend it before using it.
For larger scale projects, breakpoint-based responsive white space utilities are available in the
basscss-responsive-white-space module (not included in the default Basscss).
