    </div>

这是我的css(问题)

ul.mainmenu:
{
 list-style:none;
}

ul.mainmenu li
 {
    display: inline-block;
}

ul.mainmenu li a {
    text-decoration: none;
    background: #ff005a;
    color: #fff;
    padding: 0.25em;
}

ul.mainmenu li a:hover {
    background: #ff00ff;
}

ul.mainmenu li ul.submenu {
    list-style: none;
    display: none;
}

ul.mainmenu li:hover > ul.submenu {
    position: absolute;
    display: inline-block;
    top: 40px;
}

答案 0 :(得分:0)

使用position: absolute定位的任何元素相对于其第一个父元素定位,其position属性设置为static以外的任何值(默认值),或者,在这种情况下没有具有非static位置的元素,它将相对于body元素定位。

要解决此问题,只需将position: relative分配给父元素,例如li

ul.mainmenu li {
    position: relative;
    display: inline-block;
}

只需使用topleft来正确定位“下拉菜单”。
