CSS media query to target only iOS devices

Question

Is there a @media query to target only devices running iOS?

For example:

@media (min-device-width:320px) and (max-device-width:768px) {
    #nav {
        yada: yada;
    }
}

Would this also alter the behavior of the page on Android devices with these device widths?

Answer 1

Yes, you can.

@supports (-webkit-touch-callout: none) {
  /* CSS specific to iOS devices */ 
}

@supports not (-webkit-touch-callout: none) {
  /* CSS for other than iOS devices */ 
}

YMMV.

It works because only Safari Mobile implements -webkit-touch-callout: https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-touch-callout

Please note that @supports does not work in IE. IE will skip both of the above @support blocks above. To find out more see https://hacks.mozilla.org/2016/08/using-feature-queries-in-css/. It is recommended to not use @supports not because of this.

Warning: iOS may remove support for this in any new iOS release in the coming years. You SHOULD try a bit harder to not need the above CSS. An earlier version of this answer used -webkit-overflow-scrolling but a new iOS version removed it.
