Question

我想创建一个带有下拉菜单的导航栏，但是我的下拉菜单与主菜单重叠。我想将下拉菜单放在主菜单下。我如何将带有div标签的下拉菜单稍微向下移动以与主菜单的结尾匹配。稍后，我将其隐藏起来，并且仅在将鼠标悬停在主菜单选项上时才可用。

我修复了您的代码，并在悬停时显示了下拉列表。我认为这会对您有所帮助

rev = (rev * 10) +temp

  header {
            background-color: #5495ff;
            color: white;
            padding: 35px;
    }
    #gtu-header-home {
        text-align: center;
        font-weight: lighter;
        font-size: 3.5em;
        font-family:'Barlow', sans-serif;
        text-shadow: -1px 0px blue, 0px 1px blue, 1px 0px blue, 0px -1px blue;
    }
    #gtu-header-detail {
        text-align: center;
        font-family: 'Roboto', sans-serif;
        font-size: 25px;
    }
    #footer-copyright {
        text-align: center;
        font-size: 20px;
        font-family: 'Barlow', sans-serif;
    }
    footer {
        background-color: #9baac4;
        padding: 25px;
    }
    ul.navbar {
        list-style-type: none;
        margin: 0px;
        padding: 0px;
        background-color: gray;
    }
    .navbar a{
        text-decoration: none;
        display: block;
        color: white;
        padding: 20px;
    }
    .navbar li{
        font-size: 26px;
        font-family: 'Barlow', sans-serif;
        display: inline-block;
    }
    #innerlist-1, #innerlist-2 {
        background-color: white;
        position: absolute;
        min-width: 3cm;
    }
    .innerlist{
     display:none;
    }
    .navbar > li:hover .innerlist{
     display:block;
    }
    .innerlist a{
        color: gray;
        padding: 0px;
    }

我想用下拉菜单创建一个导航栏，但是我的下拉菜单会覆盖我的主菜单
