Styling the confirmation messages.

I copied the following CSS from an earlier post (http://www.gravityhelp.com/forums/topic/confirmation-box-styling-vanished-in-16312) and entered it in my custom CSS. There was absolutely no change to my notification messages:

[css]
body #gforms_confirmation_message {
    background-color: #FFFAC6;
    border: 1px solid #E6DB55;
   margin: 10px auto;
   padding: 30px 10px;
   width: 90%;
    font-size: 1.4em;
   color: #222;
   text-align: center
	}

Form is at http://writerscelebratewriters.com/submit-a-memoir/, and the introductory text is a confirmation message built in to the form. I'm using Headway.

OK. I'm sorry for any confusion. I have been working on it and an earlier post to the forum that I made I have since resolved on my own. But what I'm trying to change is the confirmation message(s) that appear AFTER someone succeeds at what they were trying to do. For example: http://awesomescreenshot.com/009efsi7d

I can't seem to find the others, but there is one that confirms they have successfully submitted the memoir. It would be nice if it stood out from the rest of the text.
I have another thread here: http://www.gravityhelp.com/forums/topic/need-help-with-form-to-post-authors-bio-custom-field-conditional-description. And I included a login combo. I have solved most of this-- well enough.

I just added it, David. And I published your "post." Is there a way to style the Author's Bio part of the post? I don't see where the target would be.

I added it here in the Live CSS that Headway offers. It's where I add all my CSS. I don't know why it wouldn't show up.

Please try it now. The only response I got back is from a fellow member, not staff. But she picked up that I had used a parenthesis instead of an opening bracket for the only other rule I have entered. I know pesky little details like that can have repercussions beyond the obvious. I have correcte it now. So the entirety of what's there is this:

[css]
body.custom div.wrapper {width: 1000px;}

#gforms_confirmation_message {background: #ff0000;}
