Question

任何人都可以解释为什么导航栏位于指定的<div id="navigation >标记下方，查看以下代码：

<html>
<head>
    <link rel="stylesheet" href="css.css"/>
</head>
<body>
    <div id="container">
        <div id="title">
            <h1>Record Store</h1>
        </div>
        <div id="navigation" >
            <ul class="navbar">
                <li><a href="#">Home</a></li>
                <li><a href="#">Vinyl Stock</a></li>
                <li><a href="#">Members</a></li>
            </ul>
        </div>
    </div>
</body>
</html>

和CSS

* {
 border: 0;
 padding: 0;
}

#container {
    margin: auto;
width: 800px;
border: 1px solid black;
min-height: 600px;
z-index: -9;
}

#title {

margin:auto;
border: 1px solid black;
}

#navigation{
border: 1px solid black;
height: auto;
background-color: yellow;
}


.navbar {
}

.navbar ul {
}
.navbar li {

    float: left;
    font: bold 12px/1.2em Arial, Verdana, Helvetica;
    height: auto;
    list-style: none;
    text-align: center;
    width: 33%;
    display: inline;
}
.navbar a {
    border-right: 1px solid #1F5065;
    color: black;
    display: block;
    padding: 10px 10px;
    text-decoration: none;
}

如果有人能帮助我整理酒吧，我将不胜感激。我是学习CSS和HTML的初学者。

因为您正在浮动列表元素而不清除它们。将其添加到您的CSS

.clearfix:before, .clearfix:after { content: " "; display: table; }
.clearfix:after { clear: both; }
.clearfix { *zoom: 1; }

然后将clearfix类添加到ul.navbar

        <ul class="navbar clearfix">
            <li><a href="#">Home</a></li>
            <li><a href="#">Vinyl Stock</a></li>
            <li><a href="#">Members</a></li>
        </ul>

div外的导航栏
