tip: how to remove white border above page / sidebar

Took me forever to isolate the CSS that controlled the white border above the sidebars, because I was looking for border:1px when the ‘border’ was being created using a box shadow!

#page .container-inner { background: #fff;
-webkit-box-shadow: 0 -1px 0 #fff, 0 1px 1px rgba(0,0,0,0.1);
box-shadow: 0 -1px 0 #fff, 0 1px 1px rgba(0,0,0,0.1); }

I made it #page .container-inner { 0 0 0 0} and that removed the white border. I don’t know if that’s the proper way to do it, but it worked!
