css - 居中菜单

Question

我不明白为什么我的菜单没有居中。我尝试了从内联元素到边距的所有方法:0 auto；对齐=“中心”，我无法让菜单居中。你可以在这里看到它http://jeremyspence.net78.net你必须一直向下滚动才能看到它，只有当它经过主菜单时才会出现。这是一些 CSS

.scrollmenu {
    display:none;
    position: fixed;
    top: 0;
    text-align:center;
    margin: 0px auto;
    width: 1020px;
    z-index: 10000;
    padding:0;
}
.scrollmenu li{
    width: 200px;
    height: 75px;
    overflow: hidden;
    position: relative;
    float:left;
