Question

I need to develop some html pages for iphone/android phones, but what is the difference between max-device-width and max-width? I need to use different css for different screen size.

@media all and (max-device-width: 400px)

@media all and (max-width: 400px)

What’s the difference?

Answer 1

max-width is the width of the target display area, e.g. the browser

max-device-width is the width of the device’s entire rendering area, i.e. the actual device screen

Same goes for max-height and max-device-height naturally.
