Correct way to build forms [closed]

I'm currently building a signup form and I find myself resorting to tables in order to align things properly e.g. the MySpace equivalent where I would use a colspan to achieve the even spacing between the three birthday text areas and the other text inputs. Is this going against conventions and should I be looking into more advanced CSS?

How do you close a form?

Once you've selected your form, click the Responses tab at the top of the editor. This will take you to a page where you can view and manage form responses. By default, the Accepting responses button is on. To close your Google Form, simply toggle it off.

How do I close a form response?

Open your form in Google Forms and go to the Responses tab at the top. Turn off the toggle for Accepting Responses.

I think you should drop the table all together and use more CSS. You could look into this: http://www.webcredible.co.uk/user-friendly-resources/css/css-forms.shtml
