Hello, 
I created a new module in the header as per your instructions here http://www.joomla51.com/tutorials/item/creating-a-new-module-position-in-the-header-area-of-your-template
The module displays correctly in the center of the page on the desktop but is off the screen to the right on the mobile.  How can I get it centered on the mobile as well?  The CSS I used is below.
#newmodule {
	height:50px; 
	margin:0;  
	padding:0;  
	position: absolute;
	left:400px;
	top:115px;
	width:400px;
	z-index:999;
}
