@media screen and (orientation:portrait) {
// Portrait mode
}
@media screen and (orientation:landscape) {
// Landscape mode
}
Ou inclure une orientation JavaScript :
document.addEventListener("orientationchange", function(event){
switch(window.orientation)
{
case -90: case 90:
/* Device is in landscape mode */
break;
default:
/* Device is in portrait mode */
}
});
