SASS Margin and Padding Helpers Loop. Generates .m-t-10 type helper classes.

_spacing-helpers.scss

/*
This .scss loop will create "margin helpers" and "padding helpers" for use in your web projects.
It will generate several classes such as:

.m-r-10 which gives margin-right 10 pixels.
.m-r-15 gives MARGIN to the RIGHT 15 pixels.
.m-t-15 gives MARGIN to the TOP 15 pixels and so on.

.p-b-5 gives PADDING to the BOTTOM of 5 pixels
.p-l-40 gives PADDING to the LEFT of 40 pixels

The first letter is "m" or "p" for MARGIN or PADDING
Second letter is "t", "b", "l", or "r" for TOP, BOTTOM, LEFT, or RIGHT
Third letter is the number of spacing in pixels. Adjust the amounts generated by editing the $spaceamounts variable below.

*/

$spaceamounts: (5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 75, 100); // Adjust this to include the pixel amounts you need.
$sides: (top, bottom, left, right); // Leave this variable alone

@each $space in $spaceamounts {
  @each $side in $sides {
    .m-#{str-slice($side, 0, 1)}-#{$space} {
      margin-#{$side}: #{$space}px !important;
    }
  
    .p-#{str-slice($side, 0, 1)}-#{$space} {
      padding-#{$side}: #{$space}px !important;
    }
  }
}


/*
  RUN GULP to generate the classes. Now you can use these helpers to customize spacing on HTML elements.

You could include a media queries like this:

$sides: (
"": "",
"t": "top",
"b": "bottom",
"l": "left",
"r": "right",
);

$breakpoints: (
"": "",
"xs": 576px,
"sm": 768pxm,
"md": 992px,
"lg": 1200px,
);

@each $breakName, $breakValue in $breakpoints {
  @each $sideName, $sideValue in $sides {
    @for $i from 0 through 10 {
      
      $property: if($sideName == '', '', -#{$sideValue});
      $space: $i * 10;
      $selector: '';

      @if $breakName != "" {
        $selector: #{$sideName}-#{$breakName}-#{$i};
      } @else {
        $selector: #{$sideName}-#{$i};
      }

      @if $breakName != "" {
        @media (min-width: $breakValue) {
          .m#{$selector} {
            margin#{$property}: #{$space}px;
          }
  
          .p#{$selector} {
            padding#{$property}: #{$space}px;
          }
        }
      } @else {
        .m#{$selector} {
          margin#{$property}: #{$space}px;
        }

        .p#{$selector} {
          padding#{$property}: #{$space}px;
        }
      }
    }
  }
}

Generates

.mt-4 {
  margin-top: 40px; }

.pt-4 {
  padding-top: 40px; }

@media (min-width: 576px) {
  .mt-xs-4 {
    margin-top: 40px; }

  .pt-xs-4 {
    padding-top: 40px; } }

etc...

hi,
Can you please create another loop like: py-1, px-1, where compiled css will be like padding-right:10px; padding-left:10px; padding-top-:10px; padding-bottom:10px;

Cool) Thx)

spaceamounts

I want to loop for spaceamounts too. like 1,2,3,4, and so on instead of set fix value like (5,10,20,50)

its cools , i kind of like it!!!

good job!!!

Is there a way to do this using rems rather than pxs ?

@elliotrpmorris, I run it like this;

$spaceamounts: (0, 1, 2, 3, 4, 5, 6, 7); // Adjust this to include the pixel amounts you need.
$sides: (top, bottom, left, right); // Leave this variable alone

@include media-breakpoint-up(md) {
  @each $space in $spaceamounts {
    @each $side in $sides {
      .m#{str-slice($side, 0, 1)}-#{$space} {
          margin-#{$side}: #{$space}rem !important;
      }
    
      .p#{str-slice($side, 0, 1)}-#{$space} {
        padding-#{$side}: #{$space}rem !important;
      }
    }
  }
}

And I'm adding a breakpoint size modifier using a scale basis;

$scale-xs: 0.75;
$scale-sm: 0.8;
$scale-md: 0.85;
$scale-lg: 0.9;
$scale-xl: 0.95;

This is wonderful, thank you

$spaceamounts: (2, 5, 8, 10, 15, 20, 25, 30, 35, 40, 45, 50, 75, 100);
$sides: (all, x, y, top, bottom, left, right);

@mixin make-space($prefix, $property) {
  $property-prefix: #{str-slice($property, 0, 1)};

  @each $space in $spaceamounts {
    @each $side in $sides {

      @if $side == 'all' {
        .#{$prefix}-#{$property-prefix}-#{$space} {
          #{$property}: #{$space}px !important;
        }
      } @else if $side == 'x' or $side == 'y' {
        .#{$prefix}-#{$property-prefix}#{$side}-#{$space} {

          @if $side == 'x' {
            #{$property}-left: #{$space}px !important;
            #{$property}-right: #{$space}px !important;
          } @else {
            #{$property}-top: #{$space}px !important;
            #{$property}-bottom: #{$space}px !important;
          }
        }
      } @else {
        .#{$prefix}-#{$property-prefix}#{str-slice($side, 0, 1)}-#{$space} {
          #{$property}-#{$side}: #{$space}px !important;
        }
      }
    }
  }
}

@media (min-width: 1px) {
  @include make-space(xs, margin);
  @include make-space(xs, padding);
}

@media (min-width: 768px) {
  @include make-space(md, margin);
  @include make-space(md, padding);
}

.m-t-5 {
  margin-top: 5px; }

.p-t-5 {
  margin-top: 5px; }

.m-b-5 {
  margin-bottom: 5px; }

.p-b-5 {
  margin-bottom: 5px; }

It's just margin in all css classes. even in padding class too

Just want to throw my solution in. This will take care of x / y axis and all sides. However it does not include breakpoints.

@use './variables'; <--- This would be your variable file or you can hard code values in $spacing-values below

Just dropping this for anyone who gets here:

• it handles all sides

$spacings: (1,2,3,4,5,auto);

$sides: (
  't': 'top',
  'b': 'bottom',
  'l': 'left',
  'r': 'right',
  'a': ('top', 'left', 'bottom', 'right'),
  'x': ('left', 'right'),
  'y': ('top', 'bottom'),
);

@each $space in $spacings {
    @each $prefix, $positions in $sides {
      .p#{$prefix}-#{$space} {
        @each $pos in $positions {
            padding-#{$pos}: if($space == auto, $space, #{$space * 0.25}rem);
        }
      }
      .m#{$prefix}-#{$space} {
        @each $pos in $positions {
            margin-#{$pos}: if($space == auto, $space, #{$space * 0.25}rem);
        }
      }
  }
}

A little optimization :

$spaceamounts: (0, 1, 2, 3, 4, 5, 6);
$sides: (top, bottom, left, right);

@each $space in $spaceamounts {
  @each $side in $sides {

    $unity: if($space == 0, '', em !important);

    }
    .p#{str-slice($side, 0, 1)}-#{$space}, .p#{$parallel}-#{$space}, .p-#{$space} {
      padding-#{$side}: #{$space}#{$unity};
    }
  }
}
