Thank you, I played a little around and found this looks nice, it adds two little shadows to the footer and the bottom of the page:
.site-footer {
-webkit-box-shadow: 0 -5px 20px 1px rgba(0,0,0,.12);
-moz-box-shadow: 0 -5px 20px 1px rgba(0,0,0,.12);
box-shadow: 0 -5px 20px 1px rgba(0,0,0,.12);
}
.inside-article {
-webkit-box-shadow: 0 10px 6px -6px rgba(0,0,0,0.25);
-moz-box-shadow: 0 10px 6px -6px rgba(0,0,0,0.25);
box-shadow: 0 10px 6px -6px rgba(0,0,0,0.25);
}
