Update: I’ve also found a different method, this time instead using a Python script called “Glue“.

I did this about 12 months, but recently had to setup a new development environment.
Here are some notes on setting up css-sprite.

1. Install node.js
2. Install css-sprite

   npm install css-sprite -g

3. Have fun.

Usage:

1. Create two folders src (add png files here) and images
2. run the command from cmd:

   css-sprite images/ src/*.png -p scss -s sprite.scss 

3. (Here I'm using scss, you can choose from LESS, SCSS or CSS, depending on the project).
