Compass Sprite Base

These mixins are useful for working with sprites. This file is imported by magic sprite imports.

See the Spriting Tutorial for more information.

This file can be imported using: @import "compass/utilities/sprites/base"

Mixins

=sprite-dimensions($map, $sprite)
  height: image-height(sprite-file($map, $sprite))
  width: image-width(sprite-file($map, $sprite))
@mixin sprite-dimensions($map, $sprite) {
  height: image-height(sprite-file($map, $sprite));
  width: image-width(sprite-file($map, $sprite));
}

Set the width and height of an element to the original dimensions of an image before it was included in the sprite.

view source

=sprite-background-position($map, $sprite, $offset-x: 0, $offset-y: 0, $use-percentages: false)
  background-position: sprite-position($map, $sprite, $offset-x, $offset-y, $use-percentages)
@mixin sprite-background-position($map, $sprite, $offset-x: 0, $offset-y: 0, $use-percentages: false) {
  background-position: sprite-position($map, $sprite, $offset-x, $offset-y, $use-percentages);
}

Set the background position of the given sprite $map to display the sprite of the given $sprite name. You can move the image relative to its natural position by passing $offset-x and $offset-y. The background-position will be returned in pixels. By passing true for$use_percentages`, you get percentages instead.

  @include sprite-background-position($map, $sprite, $offset-x, $offset-y, $use-percentages);
  @if $dimensions {
    @include sprite-dimensions($map, $sprite);
  }
  @if $use-magic-selectors {
    @include sprite-selectors($map, $sprite, $sprite, $offset-x, $offset-y, $use-percentages, $separator);
  }
}

Include the position and (optionally) dimensions of this $sprite in the given sprite $map. The sprite url should come from either a base class or you can specify the sprite-url explicitly like this:

background: $map no-repeat;
view source

=sprites($map, $sprite-names, $base-class: false, $dimensions: false, $prefix: sprite-map-name($map), $offset-x: 0, $offset-y: 0, $use-percentages: false, $separator: $default-sprite-separator)
  @each $sprite-name in $sprite-names
    @if sprite_does_not_have_parent($map, $sprite-name)
      $full-sprite-name: #{$prefix}#{$separator}#{$sprite-name}
      @if sprite_has_valid_selector($full-sprite-name)
        .#{$full-sprite-name}
          @if $base-class
            @extend #{$base-class}
          +sprite($map, $sprite-name, $dimensions, $offset-x, $offset-y, $use-percentages, $separator: $separator)
@mixin sprites($map, $sprite-names, $base-class: false, $dimensions: false, $prefix: sprite-map-name($map), $offset-x: 0, $offset-y: 0, $use-percentages: false, $separator: $default-sprite-separator) {
  @each $sprite-name in $sprite-names {
    @if sprite_does_not_have_parent($map, $sprite-name) {
      $full-sprite-name: #{$prefix}#{$separator}#{$sprite-name};
      @if sprite_has_valid_selector($full-sprite-name) {
        .#{$full-sprite-name} {
          @if $base-class {
            @extend #{$base-class};
          }
          @include sprite($map, $sprite-name, $dimensions, $offset-x, $offset-y, $use-percentages, $separator: $separator);
        }
      }
    }
  }
}

Generates a class for each space separated name in $sprite-names. The class will be of the form .-.

If a base class is provided, then each class will extend it.

If $dimensions is true, the sprite dimensions will specified. Positions are returned in pixel units. Set $use_percentages to true to instead get percentages.
