Five Footer Color Change

I've tried every suggestion i can find for changing the background footer color on five template and none of the custom codes are working. Very new to this, what am I doing wrong?

Post a link to your site so that we (I or someone else) can give you custom code that will work for your site.

past this code in custom css box.

#page-footer-wrapper {
   border-top: 1px solid #e8e8e8;
   clear: both;
   background-color: #000000;  /*adjust color for bg*/
}
