Staff background.

I have seen that every staff member here have orange gradient background on their posts, how can I do that? I checked the other "how to change the background" topics, but it is looking not good when I do it. I want to know how to do this gradient on the post.

Edit: Worked. I changed the "/*Your CSS To Style The Post Here*/" with a CSS gradient generator code from this website. http://www.colorzilla.com/gradient-editor/ Just adjust your gradient with the tool =] Thank you Rideem3.

Just edited [before you post] I found it, and tried to replace the code. Worked. Thank you again =]
