I wrote some CSS code to make an HTML page fit better in mobile browsers. To be sure that my CSS apply only on mobiles, I use to following media query :

@media only screen and (max-device-width: 480px)

As an iPhone developer, I tested on this device and it works really well. But I want my CSS to be use on all kind of devices (Android, Windows Phone, etc).

What would be a good resolution that would fit most of smartphone of these days? Or do I need a more complex media query?

css mobile media-queries
