How do i attach CSS styles to a form?

I see there is a render styling, but if i would like to customize the look of the form with CSS how would i do it?

I know this probably isn’t the best answer there is, but I just duplicated one of the default themes, renamed everything, then added the CSS I wanted to the new theme.

Basic, but it worked!

Good way to start understanding the structure of the themes too!

Oh … this method of theming applies to forms too… so there isnt a simpler way of just attaching a link to the css in the form, and include or something.
