Color change for header in Blackbird

Hi.
I've read here how to change the color for the header in Blackbird.

I've changed it to:

}
.menu_wrapper {
background:none
background-color:#96a37f
height:54px;
margin-top:20px;

}

However, now the background color for the header has completely disappeared.

Can you please provide some help.

Thanks.

 

Remove your old code completely and
Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.menu_wrapper {
background:none;
background-color:red;
}

This will solve your issue.
