Mixin doesn't support background-size cover or contain

[jeffdaley]

@include at2x('imagename', jpg, contain); outputs to background-size: contain, auto,which is invalid.

I could try @include at2x('imagename', jpg, contain, contain);, but that's also invalid.

Thanks for taking a look. Appreciate any help!

Hi @jeffdaley,

Take a look at https://github.com/imulus/retinajs/blob/2.0/src/_retina.scss
You should find what you're looking for in that mixin.
