This is some markup that came with the Bootstrap 4 official themes custom LESS– converted into SCSS of course. Makes it super fast/easy to style spacing in html (css classes). Enjoy.
Positioning:
.pos-r { position: relative !important; }
.pos-a { position: absolute !important; }
.pos-f { position: fixed !important; }
Width:
.w-sm { width: 25% !important; }
.w-md { width: 50% !important; }
.w-lg { width: 75% !important; }
.w-full { width: 100% !important; }
Margin and padding:
Assign margin
or padding
to an element or a subset of it’s sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. All classes are multiples on the global default value, 20px.

Responsive text alignment:
Use these classes to easily switch text-align
across viewports when designing responsive pages.
.text-xs-left { text-align: left; }
.text-xs-right { text-align: right; }
.text-xs-center { text-align: center; }
@media (min-width: @screen-sm-min) {
.text-sm-left { text-align: left; }
.text-sm-right { text-align: right; }
.text-sm-center { text-align: center; }
}
@media (min-width: @screen-md-min) {
.text-md-left { text-align: left; }
.text-md-right { text-align: right; }
.text-md-center { text-align: center; }
}
@media (min-width: @screen-lg-min) {
.text-lg-left { text-align: left; }
.text-lg-right { text-align: right; }
.text-lg-center { text-align: center; }
}
Edit: If anyone wants more, just let me know. I especially like the text/type classes as well.
