Button Alignment MailChimp Sign Up

I've added the code referenced from the forum but still unable to get the button line up correct beside the field. My site is http://www.neuic.com the submit form is at the bottom of the site and on the side bar of the blog. I would like the email field longer, if I select large in the form settings it doesn't leave any room for the button.

Current code I've added to my style.css:

[css]
/* make the form container relative for positioning */

body #gform_wrapper_2 {
    position: relative;
}

/* resize and position the form footer with the button */

body #gform_wrapper_2 .gform_footer {
width: auto;
position: absolute;
padding: 0;
margin: -40px 180px 0 0;

}

You also have to make a new form and code it for the side bar as the top/left px will be off for it.

I went with this code instead seems to work better this way for responsive websites.

[css]
body #gform_wrapper_2 .gform_footer input#gform_submit_button_2 {
   	width: 100%;
}
