Stylus-Lemonade
Stylus-Lemonade is a plugin for Node.js Stylus
which allows you to use functions like sprite-position()
, sprite-height()
, image-width()
, sprite-map()
, etc.
within your *.styl
markup to automatically fetch images and generate css sprites at render time.
If you come from the Ruby on Rails community, you will immediately recognize conventions from Spriting with Compass/SASS, originally Lemonade.
Install
sudo apt-get install libgd2-xpm-dev # on ubuntu; a libgd dependency
npm install stylus-lemonade

$animated_flame = sprite-map('flame')
#flame
background: url(sprite-url($animated_flame)) no-repeat
height: sprite-height($animated_flame, 'flame_a_0001')
width: sprite-width($animated_flame, 'flame_a_0001')
.flame-frame-1
background-position: sprite-position($animated_flame, 'flame_a_0001') !important
.flame-frame-2
background-position: sprite-position($animated_flame, 'flame_a_0002') !important
.flame-frame-3
background-position: sprite-position($animated_flame, 'flame_a_0003') !important
.flame-frame-4
background-position: sprite-position($animated_flame, 'flame_a_0004') !important
.flame-frame-5
background-position: sprite-position($animated_flame, 'flame_a_0005') !important
.flame-frame-6
background-position: sprite-position($animated_flame, 'flame_a_0006') !important
Will output CSS like this:
#flame {
background: url(../images/flame-4e9c94d3fa.png) no-repeat;
height: 512px;
width: 512px;
}
.flame-frame-1 {
background-position: 0 0 !important;
}
.flame-frame-2 {
background-position: 0 -512px !important;
}
.flame-frame-3 {
background-position: 0 -1024px !important;
}
.flame-frame-4 {
background-position: 0 -1536px !important;
}
.flame-frame-5 {
background-position: 0 -2048px !important;
}
.flame-frame-6 {
background-position: 0 -2560px !important;
}
And the image will turn out like this:
