我已经对可能的解决方案进行了大量的搜索和测试，但无法将此响应式菜单放在中央位置。

以下是我一直试图让它发挥作用的地方：http://jsfiddle.net/

每当我更改位置：绝对时，悬停时的菜单格式错误。我还尝试了保证金：0自动; 等，但我尝试过的任何内容都无法使用，我尝试删除浮动。任何帮助都非常感谢。树

放

display: table;
margin: 0 auto;

在ul标签中，如下所示：

ul {
    list-style-type:none;
    margin: 0;
    padding:0;
    display: table;
    margin: 0 auto;
}
