在CSS中，.在类名前书面和#的ID之前写的。

你还没有在你的css中做过这件事。

CSS：

.sidemenu { 
    width:200px; 
    height:auto; 
    margin-top:150px; 
} 
#sidenav ul { 
    float: left; 
    padding: 0; 
    border-bottom: none; 
    list-style: none; 
} 
#sidenav li { 
    list-style:none; 
    position: relative; 
} 
#sidenav li a { 
    padding: 1em 2em; 
    text-decoration: none; 
    color:#000000; 
    float: left;   
} 
#sidenav li a:hover { 
    background: #6666CD; 
    background: -moz-linear-gradient(top, #11032e, #6666CD); 
    background: -webkit-gradient(linear, left top, left bottom, from(#11032e), to(#2a0d65)); 
    border:2px solid #000000; 
    border-radius:20px; 
    color:#FFFFFF; 
} 
#sidenav li ul { 
    overflow:hidden; 
    display: none; 
    position: absolute; 
    left: 130px; 
    padding: 0; 
    margin: 0; 
} 
#sidenav li:hover > ul { 
    display: block; 
} 
#sidenav li ul li, #sidenav li ul li a { 
    float: none; 
} 
#sidenav li ul li { 
    display: inline; 
} 
#sidenav li ul li a { 
    width: 120px; 
    display: block; 
} 
#sidenav li ul li ul { 
    display: none; 
} 
#sidenav li ul li:hover ul { 
    left: 100%;
