Can validate fields using space
Hi. I have two questions, perhaps someone can help me with.
 When I validate a text field and preview it in my internet browser, I can just hit space on any text or number field and it validates. Is there a way I can set it so that you can't use just spaces to validate a field?
 Im designing an order form to sell physical goods e.g. paper weights that light up.
The form will have 2 products (different sizes), each product will have a quantity field
and a total value will be displayed when a user presses the submit button. Please can someone help me to design this using css form builder?
