How to center Language flag on mobile device?

I have a view problem that I hope you can help with. The language flag (English or Thai choice) should be centered just below the banner on my form. It is fine in a browser, but not on my mobile device... in this case an iPhone. It is cut off on the lefthand side. I fear my Thai customers are not going to catch it to change the language.

I don't find a way to change any setting. But I really need it to be easier to see on cell phones... preferable centered as in the browsers. 

Thanks,

Joette

Please insert the below CSS code in your Custom CSS field:

@media only screen and (max-device-width: 500px){

  div#langDd {

    position: relative!important;

    left: -130px!important;

    top: 50px!important;

}

}

That will make your form look like this on a mobile device:
