Question

Seems that iPad rules overwrite iPhone4 related rules.
How can I solve this problem?

/* iPad */
@media only screen and (min-device-width: 768px) and (max-device-width: 1024px) and (orientation:portrait) {
    #theDiv { width: 400px; }
}
@media only screen and (min-device-width: 768px) and (max-device-width: 1024px) and (orientation:landscape) {
    #theDiv { width: 600px; }    
}


/* iPhoneRetina */
@media only screen and (-webkit-min-device-pixel-ratio : 1.5), only screen and (min-device-pixel-ratio : 1.5) {
    #theDiv { width: 200px; }
}

Answer 1

You can bump the Retina display’s pixel ratio to 2.

Here’s the link to the Webkit blog post about it. Go down to the header “Conditional Inclusion”.
