tjhe documentation for sprite-file($map, $sprite) says it returns a relative path, however for me it is returning an absolute path.
is there a different mixin available to get the relative path of the original sprite image in the image directory to be used with an img tag?
I think this is another case where the docs and the implemented code do not match
I think what you need would be a sprite-file-url function but, this would create a problem because its assumed that you can store the raw sprite images outside of the scope of your images folder.
