Are you experiencing ugly form fields on the mobile devices which look nothing like the very cool and awesome fields which you built for the desktop version? That could be because its using the browser’s default css for the input and select fields and buttons.
I’ve experienced this on my iphone but it could happen with other mobile operating systems and browsers also.
This bit of code will eliminate that effect.
input {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}
