Can't Change Nav background in Twenty Eleven

For some reason the nav background is not pulling from my child theme. I tested this by changing the main css to this:

#access {
	background: #121212; /* for non-css3 browsers */

filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#252525', endColorstr='green'); /* for IE */
background: -webkit-gradient(linear, left top, left bottom, from(#252525), to(green)); /* for webkit browsers */
background: -moz-linear-gradient(top,  #252525,  green); /* for firefox 3.6+ */
	-webkit-box-shadow: rgba(0, 0, 0, 0.4) 0px 1px 2px;
	-moz-box-shadow: rgba(0, 0, 0, 0.4) 0px 1px 2px;
	box-shadow: rgba(0, 0, 0, 0.4) 0px 1px 2px;
	clear: both;
	display: block;
	float: left;
	margin: 0 auto 6px;
	width: 100%;
}

And it did make changes, but this is what I have in my child theme and it is not being used as the background for the nav:

#access {
background: #f0b7a1; /* Old browsers */
background: -moz-linear-gradient(top,  #f0b7a1 0%, #8c3310 50%, #752201 51%, #bf6e4e 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#f0b7a1), color-stop(50%,#8c3310), color-stop(51%,#752201), color-stop(100%,#bf6e4e)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top,  #f0b7a1 0%,#8c3310 50%,#752201 51%,#bf6e4e 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top,  #f0b7a1 0%,#8c3310 50%,#752201 51%,#bf6e4e 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top,  #f0b7a1 0%,#8c3310 50%,#752201 51%,#bf6e4e 100%); /* IE10+ */
background: linear-gradient(top,  #f0b7a1 0%,#8c3310 50%,#752201 51%,#bf6e4e 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#f0b7a1', endColorstr='#bf6e4e',GradientType=0 ); /* IE6-9 */

repeat-x;
	position: relative;
	width: 100%;
	float: left;
	padding: 0 0;
}
