Question

我正在使用纯css测试下拉导航栏。文本对齐不起作用它只对齐下拉文本，左：50％和右：50％是的它使文本中心但导航栏不会覆盖我的页面的宽度。请不要使用溢出：隐藏它会使下拉列表不可见

我想将文字设为this，但由于溢出我无法看到下拉列表

Css：

ul.dropdown, ul.dropdown li, ul.dropdown ul {
    list-style: none;
    margin: 0;
    padding: 0;
}
ul.dropdown {
    position: relative;
    z-index: 597;
    background-color: black;
}
ul.dropdown li {
    float: left;
    min-height: 1px;
    line-height: 1.3em;
    vertical-align: middle;
}
ul.dropdown li.hover, ul.dropdown li:hover {
    position: relative;
    z-index: 599;
    cursor: default;

ul.dropdown ul {

Answer 1

删除float: left;中的ul.dropdown li。在text-align: center;和ul.dropdown中display: inline-block;添加ul.dropdown li

Fiddle Demo

ul.dropdown {
    position: relative;
    z-index: 597;
    background-color: black;
    text-align: center;
}
ul.dropdown li {
    display: inline-block;
    min-height: 1px;
    line-height: 1.3em;
    vertical-align: middle;
}
