如何集中我的hmenu（无论分辨率）？

标签： css menu center

我有一个问题试图弄清楚如何恰当地集中hmenu。我已经四处搜索了，但css非常先进。我希望菜单栏像现在一样全屏，但菜单选项需要居中（无论屏幕分辨率如何）。

2 个答案:

答案 0 :(得分：0)

对于.sleep-nav设置text-align: center - 您的菜单是内联块元素，因此它将像文本一样居中，您需要删除float: left的{​​{1}}或将其设置为ul.sleep-hmenu。

答案 1 :(得分：0)

这就是我为了让它发挥作用所做的事情：

ul.sleep-hmenu {
width: 100%;
display: block;
text-align: center;
}

ul.sleep-hmenu li {
/*-Remove Float: left;-*/
}
