Here is what I am trying to do:
1. Replace gray background color of drop downs to #d8b983.
2. Replace text to #e1c47e
3. Remove top padding/margin from ALL drop downs
4. Remove bottom padding/margin from BOTTOM drop down button


nav li {
    font-size: 12pt;  
}
.nav li a, .nav li a:link, .nav li a:visited {
    color: #d8b983;  
}
.nav li a {
    border-right: 1px solid #d8b983;
    padding: 0 0.75em;
    margin: 1em 0;
}

.nav li:last-child a {
    border-right: none;
}

.nav li .sub-menu a {
    border-left: none;
      color:#e1c47e; /*yellow*/
       padding: 0 0.75em;
      margin:5px 0px;
