I have my sidebars different colors. The primary is green and the secondary is white, but the secondary sidebar near the bottom displays the green color.
Secondary Sidebar CSS:
/* set full secondary sidebar background */
.s2, .main {
background: #ffffff !important;
}
Primary Sidebar CSS:
/* set full primary sidebar background */
.s1, .main-inner {
background: #f3fbc4 !important;
}
