Finally found a solution from : Detect different device platforms using CSS
<link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait)" href="ipad-portrait.css" />
<link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:landscape)" href="ipad-landscape.css" />
To reduce HTTP call, this can also be used inside you existing common CSS file:
@media all and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait) {
.ipad-portrait { color: red; } /* your css rules for ipad portrait */
}
@media all and (device-width: 1024px) and (device-height: 768px) and (orientation:landscape) {
.ipad-landscape { color: blue; } /* your css rules for ipad landscape */
}
