Edit the input field width for mobile devices

Hello there,

We have been using your plugin for a while now, and a quite happy with it.

However, we noticed that the input field “state” is pushing the site out of the viewport on mobile devices.

Moreover, the city and post code input fields are really small (around 33%) on mobile devices, making it almost impossible to see what have been typed in the city field.

Is there any way to force the state, post code and state input fields to anything bigger, like for instance 50 or 66% for mobile devices?

Moreover, how can we force “state” to move on to the next line, instead of pushing the site out of the viewport on mobile devices?

Any assistance is much appreciated.
