How do I change the width of that single text box in the form?

A follow up question is how do I change the width of that single text box without changing all of the other text boxes in the form?

You can do that by applying this CSS:

#input_4 {

width:100px;

}

Which you will copy and paste into your Custom CSS field.

Where #input_4 is ID of the field and you can find it like this (for each field):

1. Click settings button:

2. Click Advanced - Field details:

3. You will find the field's ID below:

The above CSS you can apply to any field as long as you use the correct ID. Of course, you can change the width.

If you have any further questions or need any assistance please let us know.

Thank you!
