Simple CSS changes for contact form


I want to give my contact form:

The same look of this page:

Here's the CSS that gives the secong page its look:

.single-funder .span10 {
    width: 100% !important;

.funder .row-fluid .span10 + .span2 {display: none;}

.single-funder #sidebar {display: none;}

.single-funder .row-fluid .span8 {
width: 100%;

I tried adapting it for the contact form, but since I'm no coder, it didn't work.
