我的纯 CSS 下拉菜单有点问题,当我将 CSS 属性添加到页脚和容器 div 时,子菜单不会保持显示。

我真的不知道如何解决这个问题,我尝试在谷歌上寻找答案,但我找不到任何可以解决我的问题的答案。

* {
box-sizing: border-box;
margin: 0;
padding: 0;
font-family: OpenSans, Noto, Helvetica Neue, Helvetica, Tahoma, Arial, FreeSans, sans-serif;

header {
position: relative;
width: 100%;
height: 110px;

padding: 5px;
}
#logo {
position: absolute;
width: 100px;
height: 100px;
background: #00c308;
padding: 5px;
padding-top: 55px;
color: white;
font-weight: bold;
font-size: 12px;
}
nav {
display: flex;
justify-content: center;
border-top: 1px #D1D1D1 solid;
position: static;
width: 100%;
height: 50px;
