Jane Milburn on "Change menu navigation bar colour."

Hi, while following the steps, it appears I have already done what was instructed. In the child theme css there were some differences in the # colour which I changed but still nothing happens. Here is the CSS Imade in my Child Theme style.css file.
#access {
background: #000000; /* Show a solid color for older browsers */
background: -moz-linear-gradient(#000000, #000000);
background: -o-linear-gradient(#000000, #000000);
background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#000000), to(#000000)); /* older webkit syntax */
background: -webkit-linear-gradient(#000000, #000000);
-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%;
