Custom SCSS for_grid.scss

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.

Custom _grid.scss

Positioning:

.pos-r { position: relative !important; }
.pos-a { position: absolute !important; }
.pos-f { position: fixed !important; }

.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.

.m-a-0 { margin:        0 !important; }
.m-t-0 { margin-top:    0 !important; }
.m-r-0 { margin-right:  0 !important; }
.m-b-0 { margin-bottom: 0 !important; }
.m-l-0 { margin-left:   0 !important; }

.m-a { margin:        $spacer !important; }
.m-t { margin-top:    $spacer-y !important; }

.m-b { margin-bottom: $spacer-y !important; }
.m-l { margin-left:   $spacer-x !important; }
.m-x { margin-right:  $spacer-x !important; margin-left: $spacer-x !important; }
.m-y { margin-top:    $spacer-y !important; margin-bottom: $spacer-y !important; }

.p-r-0 { padding-right:  0 !important; }

.p-r-lg { padding-right:  ($spacer-y * 3) !important; }
.p-b-lg { padding-bottom: ($spacer-y * 3) !important; }
.p-l-lg { padding-left:   ($spacer-y * 3) !important; }
.p-x-lg { padding-right:  ($spacer-x * 3) !important; padding-left:   ($spacer-x * 3) !important; }
.p-y-lg { padding-top:    ($spacer-y * 3) !important; padding-bottom: ($spacer-y * 3) !important; }

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.
