Hi!
I think the placeholder text needs a different rule for CSS3 supported browsers.
Try something like:
[code]
@media only screen and (max-width: 980px) {
input.orig,
input.orig::-webkit-input-placeholder,
input.orig:-moz-placeholder,
input.orig::-moz-placeholder,
input.orig:-ms-input-placeholder {
font-size: 12px !important;
line-height: 15px !important;
}
}
[/code]
