Remove bars twenty eleven theme

I would assume that making a child and over-riding the CSS or commenting out something in another file would do it. I haven’t looked carefully at this theme yet, but I’ve done similar things with twenty ten.

see if this works. add this to your child css theme:

#access {
	background: none;
	-webkit-box-shadow: none;
	-moz-box-shadow: none;
	box-shadow: none;
}

Add this to child theme style.css

#page {
    margin: 0 auto;
  }
