Answer 1

Bootstrap 4 has a new notation for margin and padding classes. Refer to Bootstrap 4.0 Documentation - Spacing.

From the documentation:

Notation

Spacing utilities that apply to all breakpoints, from xs to xl, 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, and xl.

Examples

.mt-0 { margin-top: 0 !important; }

.p-3 { padding: $spacer !important; }
