How to use the Form Designer to resize form width and font color and size

I would also like to know:

- how can I resize the width of the order form to fit my website

- how can I resize the width of the columns

- how can I change the font colour and font size

You can  resize the width of your form and resize width of input fields inside of Form Designer under Form Layout option.

Font color can be changed inside Color Scheme option.

And font size can be changed inside Font Option.

Hope this will help.
