Answer 1

对 li 使用 text-align & display:inline-block: http://jsfiddle.net/dQbqP/1/

.div1 {
    margin:auto;
    text-align:center;
}
.div1 ul li {
    display:inline-block;
    list-style-type: none;
}

Answer 2

尝试这个...

body { background-color:#CCC }
.div1{
   text-align:centre;
     width:100%;
}

ul{
    width:35%;    
    display:block;
    margin:0 auto;
    padding:0px;
}

li{
    list-style:none;
    float:left;
    margin:0px;
    padding:10px;
    background-color: #333;    
}

a {
    color: #FFF;
    text-decoration: none;
}

li:hover { background-color: #666; }

li:first-child { border-radius: 8px 0px 0px 8px; }

li:last-child { border-radius: 0px 8px 8px 0px; }
