Stubborn footer padding

I have a large amount of white space below my content. I inspected with firebug and see I have some margin and padding I can get rid of on my footer. But when I add the code below to my child theme nothing seems to happen.
(In the end I plan on having nothing in my footer area)
What am I overlooking?

/* Footer */
footer[role="contentinfo"] {
	border-top: 0px solid #ededed;
	margin-top: 1px;
	margin-top: 1.714285714rem;
	padding: 1px 0;
	padding: 0.714285714rem 0;
}
