In JavaScript the orientation mode can be detected using:

if (window.innerHeight > window.innerWidth) {
    portrait = true;
} else {
    portrait = false;
}

However, is there a way to detect the orientation using CSS only?

Eg. something like:

@media only screen and (width > height) { ... }

Answer
