Sidebar Background Color won’t Change

I have been attempting to change the background color of my sidebar: https://www.restorepersonaltraining.com but can’t make it happen.
I have been placing this code: background-color: #4AA02C;
in various spots within the sidebar section which I posted below. Any help would be greatly appreciated.

/* sidebar */
#sidebar {
float: right;
width: 30%;
margin: 0 0 10px 0; padding: 0;
}
#sidebar h1 {
padding: 10px 0px 5px 10px;
margin: 0;
}
.sidebox {
background: #F2F2F2;
border: 1px solid #EFEDED;
margin-bottom: 10px;
}

/* sidebar menu */
#sidebar ul.sidemenu {
list-style:none;
margin: 10px 0;
padding: 0;
background: #F2F2F2;
}
#sidebar ul.sidemenu ul {
list-style:none;
margin: 10px 0;
padding: 0;
background: #F2F2F2;
}
#sidebar ul.sidemenu li {
padding: 0px 10px;
}
#sidebar ul.sidemenu a {
display:block;
font-weight:normal;
color: #333;
height: 1.5em;
padding:.3em 0 .3em 15px;
line-height: 1.5em;
border-top: 1px dashed #CCC;
text-decoration:none;
}
#sidebar ul.sidemenu li.sidemenubottom {
border-top: 1px dashed #D5D5D5;
margin: 0px 10px;
}
#sidebar ul.sidemenu a:hover {
padding: .3em 0 .3em 10px;
border-left: 5px solid #65944A;
color: #65944A;
}
