Margin

Bootstrap 5 Margin component

Responsive Margin built with Bootstrap 5. MDB includes a wide range of shorthand responsive margin utility classes tomodify an element’s appearance.

How it works

Assign responsive-friendly margin or padding values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from .25rem to 3rem.

Note: If you want to add margin to the left side you must use the class ms-* (margin start) instead of ml-* (margin left).

Likewise for the margin on the right: you have to use the class me-* (margin end) instead of mr-* (margin right).

Below is an example using classes for the right margin with a visual representation of their sizes. The same sizes apply to all directions (left, right, top, bottom) and for both margins and padding.

Class name Size Visual representation
.me-1 0.25rem
.me-2 0.5rem
.me-3 1rem
.me-4 1.5rem
.me-5 3rem

Notation

Spacing utilities that apply to all breakpoints, from xs to xxl, have no breakpoint abbreviation in them. This is because those classes are applied from min-width: 0 and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.

The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, xl, and xxl.

Where property is one of:

  • m - for classes that set margin
  • p - for classes that set padding

Where sides is one of:

  • t - for classes that set margin-top or padding-top
  • b - for classes that set margin-bottom or padding-bottom
  • s - (start) for classes that set margin-left or padding-left
  • e - (end) for classes that set margin-right or padding-right
  • x - for classes that set both *-left and *-right
  • y - for classes that set both *-top and *-bottom
  • blank - for classes that set a margin or padding on all 4 sides of the element

Where size is one of:

  • 0 - for classes that eliminate the margin or padding by setting it to 0
  • 1 - (by default) for classes that set the margin or padding to $spacer * .25
  • 2 - (by default) for classes that set the margin or padding to $spacer * .5
  • 3 - (by default) for classes that set the margin or padding to $spacer
  • 4 - (by default) for classes that set the margin or padding to $spacer * 1.5
  • 5 - (by default) for classes that set the margin or padding to $spacer * 3
  • auto - for classes that set the margin to auto

(You can add more sizes by adding entries to the $spacers Sass map variable.)
