Spacing

Stacks provides atomic classes to override margin and padding.

Margin

Immutable margin utilities are based on our global white space scale. These can dramatically help reduce the size of large stylesheets and allow for greater flexibility and quicker iteration when designing in the browser.

Margin 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 use.

Auto margin classes

Section titled Auto margin classes

Stacks provides additional automatic margin classes. These come in handy when positioning individual flex items within flex layouts, or horizontally centering a block-level element.

Direction	Class
All directions	.m-auto
Top	.mt-auto
Right	.mr-auto
Bottom	.mb-auto
Left	.ml-auto
X axis	.mx-auto

Padding

Section titled Padding

Immutable 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.

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 use.
