Stripe field stretches too far

Hello... I was hoping to get some CSS code help for the stripe field I've identified in my pic.  I would normally know how to do this myself, but because the field is nested within the stripe widget, I'm not sure how to.

I was hoping to have it so that regardless of what media size, the field only spans about 50% of it's available space.

Thanks in advance.

The form is @ https://form.jotform.us/70824847360157 and is embedded at the URL listed / provided.

Add this CSS code to your form:

@media only screen and (max-width: 40em){

input#input_37_donation {

width:50%!important;

}

}

Hope this will help. let us know if you need further assistance.
