SCSS Retina Backgrounds

This is a lightweight SCSS mixin to make it quicker and easier to maintain standard and @2x images in your SCSS files.

Usage

Notice that the file extension is missing in the mixins. The extension lives in the mixin.

@2x jpg/png

To add a jpg standard + @2x combo, use:

@include background-image-2x-jpg('path/to/file');

This will compile as:

background-image: url('path/to/file.jpg');

@media only screen and (-webkit-min-device-pixel-ratio: 1.5), 
 	only screen and (-o-min-device-pixel-ratio: 3/2),
  	only screen and (min-device-pixel-ratio: 1.5) {
      	background-image: url('path/to/[email protected]');
  	}

There's a background-image-2x-jpg() mixing for jpgs and background-image-2x-png() for pngs.

SVG with PNG fallback

To use an svg with a png fallback, use:

@include svg-image('branding/logo');

This will compile as:

.svg .foo { background-image: url('path/to/file.svg'); }
.no-svg .foo { background-image: url('path/to/file.png'); }
