Bleed Mixin

bleed.scss

@mixin bleed(
  $width: $grid-padding,
  $sides: left right,
  $style: $container-style
) {
  @if $border-box-sizing { @include box-sizing(content-box) }

  @if type-of($width) == 'list' {
    $width: filter($width, of);
    $width: space(nth($width,1), nth($width,2), $style);
  } @else if unitless($width) {
    $width: space($width, $style: $style);
  }

  @if $sides == 'all' {
    margin: - $width;
    padding: $width;
  } @else {
    @each $side in $sides {
      margin-#{$side}: - $width;
      padding-#{$side}: $width;
    }
  }
}

This is just exactly what I've been looking for, thank you :)
