I want to target mobile devices using CSS media queries like this:\[code\]@media (min--moz-device-pixel-ratio: 1.5), (-o-min-device-pixel-ratio: 3/2), (-webkit-min-device-pixel-ratio: 1.5), (min-resolution: 1.5dppx) { /* your retina rules here */}\[/code\]What would be the correct settings for mobile phones. Let's say I want to avoid targeting tablets and larger screens and target only mobile phones?
