# Spriting with Compass
Spriting has never been easier with Compass. You place the sprite images in a folder,
import them into your stylesheet, and then you can use the sprite in your selectors in one
of several convenient ways.

## Basic Usage

The simplest way to use these icon sprites is to let compass give you a class for each sprite:

is located within it.

## Layout Control
Set the `$<sprite>-layout` variable to the preferred layout method.
* vertical - default
* horizontal - lays images out side by side
* diagonal - lays images out corner to corner none of the spacing of padding options are taken into account
* smart - lays the images out using a bin packing algorithm which allows for much smaller surface areas in your sprite files - does not support spacing or padding
Example:
$icon-layout:horizontal;
@import "icon/*.png";
$dropcap-layout:diagonal
@import "dropcap/*.png";

sprites, you may find that hand crafting the import will speed up compilation times. See
the section on [performance considerations](#performance) for more details.
<a name="magic-selectors"></a>
## Magic Selectors
If you want to add selectors for your sprites, it's easy todo by adding `_active` `_target` or `_hover` to the file name, In the example below we have a sprite directory that looks like:
* `selectors/ten-by-ten.png`
* `selectors/ten-by-ten_hover.png`
* `selectors/ten-by-ten_active.png`
* `selectors/ten-by-ten_target.png`
Now in our sass file we add:
@import "selectors/*.png";
a {
@include selectors-sprite(ten-by-ten)
}
And your stylesheet will compile to:
.selectors-sprite, a {
background: url('/selectors-sedfef809e2.png') no-repeat;
}
a {
background-position: 0 0;
}
a:hover, a.ten-by-ten_hover, a.ten-by-ten-hover {
background-position: 0 -20px;
}
a:target, a.ten-by-ten_target, a.ten-by-ten-target {
background-position: 0 -30px;
}
a:active, a.ten-by-ten_active, a.ten-by-ten-active {
background-position: 0 -10px;
}
Alternatively you can use the `@include all-selectors-sprites;` after the import and get the following output:
.selectors-sprite, .selectors-ten-by-ten {
background: url('/selectors-sedfef809e2.png') no-repeat;
}
.selectors-ten-by-ten {
background-position: 0 0;
}
.selectors-ten-by-ten:hover, .selectors-ten-by-ten.ten-by-ten_hover, .selectors-ten-by-ten.ten-by-ten-hover {
background-position: 0 -20px;
}
.selectors-ten-by-ten:target, .selectors-ten-by-ten.ten-by-ten_target, .selectors-ten-by-ten.ten-by-ten-target {
background-position: 0 -30px;
}
.selectors-ten-by-ten:active, .selectors-ten-by-ten.ten-by-ten_active, .selectors-ten-by-ten.ten-by-ten-active {
background-position: 0 -10px;
}

## Customization Options
### Options per Sprite Map
When constructing the sprite map, the entire sprite map and it's associated stylesheet
can be configured in the following ways. Each option is specified by setting a [configuration
variable](/help/tutorials/configurable-variables/) before importing the sprite. The variables
are named according to the name of the folder containing the sprites. In the examples below
the sprites were contained within a folder called `icon`.
* `$<map>-spacing` -- The amount of transparent space, in pixels, around each sprite.
Defaults to `0px`. E.g. `$icon-spacing: 20px`.
* `$<map>-repeat` -- Wether or not each sprite should repeat along the x axis. Defaults
to `no-repeat`. E.g. `$icon-repeat: repeat-x`.
* `$<map>-position` -- The position of the sprite in the sprite map along the x-axis. Can
be specified in pixels or percentage of the sprite map's width. `100%` would cause the
sprite to be on the right-hand side of the sprite map. Defaults to `0px`.
E.g. `$icon-position: 100%`.
* `$<map>-sprite-dimensions` -- Whether or not the dimensions of the sprite should be
included in each sprite's CSS output. Can be `true` or `false`. Defaults to `false`.
* `$<map>-sprite-base-class` -- The base class for these sprites. Defaults to `.<map>-sprite`.
E.g. `$icon-sprite-base-class: ".action-icon"`
* `$<map>-clean-up` -- Whether or not to removed the old sprite file when a new one is created. Defaults to true
### Options per Sprite
When constructing the sprite map, each sprite can be configured in the following ways:
* `$<map>-<sprite>-spacing` -- The amount of transparent space, in pixels, around the sprite. Defaults
to the sprite map's spacing which defaults to `0px`. E.g. `$icon-new-spacing: 20px`.
* `$<map>-<sprite>-repeat` -- Wether or not the sprite should repeat along the x axis. Defaults
to the sprite map's repeat which defaults to `no-repeat`. E.g. `$icon-new-repeat: repeat-x`.
* `$<map>-<sprite>-position` -- The position of the sprite in the sprite map along the x-axis. Can
be specified in pixels or percentage of the sprite map's width. `100%` would cause the
sprite to be on the right-hand side of the sprite map. Defaults to the sprite map's
position value which defaults to `0px`. E.g. `$icon-new-position: 100%`.
