Centre Header on mobile devices

Howdy,

On this site when the screen is viewed on a iPhone the logo "Devina" goes off center.
See attached image.

The theme support people suggested this, but it's not doing the trick:

@media only screen and (max-width: 1000px)
.q_logo a {
left: 0 !important;
}
}
Please advise.

Thanks,
Casper
