website shifted to left

I changed the wrapper for the navigation so it would not go across the page. When added the width it shifted the web page to the left, before it was centered down the middle.

my css has this

#wrapper {
background: url(images/wrapper-bg.png) left 236px repeat-x;
width: 950px;
align: center;

the align:center is not putting it back to the center

Any suggestions how to fix this?

thanks
