Add this line of code to line 261 in the header section. (You'll need an editor like notepad++) It's in the first group of code after the hack for the header /*----------Header----------*/
box-shadow: 0px 10px 5px #888888;
Here is an image to help.
Enter a carriage return at the end of line 260
background-color: orchid;
then enter the box shadow code on the new line created, line 261.
Save and upload and viola, you have a new looking header!
