Contact Form – reduce some elements to 50% and on one line

Hi,

I’d like to style the form like this: and if that link doesn’t work: http://screencast.com/t/VJwcoNdf

I can reduce the text areas to 50% or less but can’t see how to shift them on to the same line as the label, input and p aren’t wrapped in one element.

Is this possible or would I need to install another contact form plugin?

Thanks.
