42## Example

46```css
47@media
48 only screen and (-webkit-min-device-pixel-ratio: 2),
49 only screen and ( min--moz-device-pixel-ratio: 2),
50 only screen and ( -o-min-device-pixel-ratio: 2/1), /* Opera */
51 only screen and ( min-device-pixel-ratio: 2),
52 only screen and ( min-resolution: 192dpi), /* fallback */
53 only screen and ( min-resolution: 2dppx) {
