change width of text field

I need to make some of these fields less wide and the only instructions I can find involve changing the css. Like City and State shouldn't be that wide.

Is it true that to change the width of a field we have to figure out the css?

Thanks for your help!

I have inspected your form and I saw that you added Custom CSS code to change the width of city, state and email fields. 

You can change width values in CSS to increase/decrease width of those fields.

You can also remove CSS code and then change the width of the fields inside of Form Builder. Simply select the field, click on Size option and change the values. 

For City and state you can also add Address field to your form and remove all other field options.

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