Section Title Background + CSS Ready Alignment

Have a couple of issues of a fairly large form I'm working on. here

http://randydueck.com/darren/re-meeting-questionnaire/

I'm using Headway Themes, and just upgraded to the most recent version of Gravity Forms.

First, I'm attempting to change the background color of the section break but it's not working, the other css elements for the section work, but not the bg element ??? Here's the code I've used.
'body #gform_wrapper_3 {margin-left: 15px;}
body #gform_wrapper_3 .gform_body .gform_fields .gsection {border-bottom: 1px solid #222; border-top: 1px solid #222; background: #ddd;}'

As you can see on the form, I'm using the gf_left_half class and gf_right_half for the fields, but they're messed up. How can I fix them so they're aligned?

Also having issues with the section title alignment. It seems that the CSS isn't working. Here's my full CSS

'body #gform_wrapper_3 .gform_body .gform_fields .gsection {border-bottom: 1px solid #222; border-top: 1px solid #222;}
body #gform_wrapper_3 .gform_body .gform_fields h2.gsection_title {position: relative; background: #ddd; margin-top: -15px;}'

Thanks for your help.
