【问题描述】：

my sad navbar here 我无法让导航栏水平显示，并尝试将浮动、位置和 display:inline-block 搞乱。它是 ul 格式，中间有 3 个带有下拉菜单的按钮。如果您发现我做错了什么，请告诉我，谢谢！

    /* NAVIGATION BAR */
#nav {
    width: 1100px;
    height: 200px;
    float: left;
    font-weight: bold;
    font-size: 24px;
    float: left;
    }

# nav button {
    display: inline-block;
    position: relative;
    width: 100%;
    float: left;
    }

ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    width: 100%
    background-color: white;
    color: rgb(36,60,131);
    font-family: "Century Gothic", CenturyGothic, AppleGothic, sans-serif;
    display: inline-block;
    }

li {
    float: left;
    }

/* nav bar hover */
li a {
    display: inline-block;
    color: #000;c
    text-align: center;
    padding: 8px 16px;
    background-color: white;
    color: rgb(36,60,131);
    text-decoration: none;
    font-family: "Century Gothic", CenturyGothic, AppleGothic, sans-serif;
    float: left;
    border-left: 1px solid #bbb;
    border-right: 1px solid #bbb;
    }

/* changes link color on hover */
li a:hover, .dropdown:hover .dropbtn {
    background-color: rgb(36,60,131);
    color: white;
    }

/* highlights active page on nav bar */
.active {
    background-color: rgb(36,60,131);
    color: white;
    }

li.dropdown {
    display: inline-block;
    }

/* dropdown menu */
.dropbtn {
    display: inline-block;
    background-color: white;
    text-align: center;
    padding: 8px 16px;
    color: rgb(36,60,131);
    font-family: "Century Gothic", CenturyGothic, AppleGothic, sans-serif;
    text-decoration: none;
    font-size: 24px;
    border: none;
    font-weight: bold;
    border-left: 1px solid #bbb;
    border-right: 1px solid #bbb;
    }

.dropdown-content {
    display: none;
    position: absolute;
    background-color: rgb(36,60,131);
    color: white;
    min-width: 160px;
    }

.dropdown-content a {
    padding: 8px 16px;
    background-color: white;
    color: rgb(36,60,131);
    text-decoration: none;
    display: block;
    text-align: left;
    }

.dropdown-content a:hover {
    background-color: rgb(36,60,131);
    color: white;
    }

.dropdown:hover .dropdown-content {
    display: block;
    }

标签： html css navbar

【解决方案1】：

给你：https://jsfiddle.net/2uj2u5g5/

您忘记将; 添加到width:100% 之一，因此CSS 无法正常工作。您还做了li.dropdown，而您的下拉类不在li 内，所以这也不起作用。我强烈建议您在导航面板中添加更多结构并牢记 HTML 标准。请关注一些像这样的知名文章：http://www.w3schools.com/css/css_navbar.asp。

祝你好运。
