html - 导航栏重新定位的问题

问题描述

我正在创建我的网站，并注意到带有下拉列表的导航栏的位置比我想要的低很多。我立即尝试使用一些不同的方法，例如边距和填充、位置：固定和位置：绝对以及设置与顶部的距离，但这几乎删除了我的下拉列表。我很想知道为什么会发生这种情况以及我可以做些什么来修复我的代码。

h1 {
	font-size: 54px;
	font-family: 'Kalam', cursive;
	margin: 10px;
	color: white;
}
body {
	background: url("flowers.jpg") no-repeat fixed;
}


.navbar {
    overflow: hidden;
    background-color: #333;
    font-family: 'Poiret One', cursive;
	background-color: rgba(249, 197, 249, 0.5);
	width: 100%;
}

.navbar a {
    float: left;
    font-size: 16px;
    color: white;
    text-align: center;
    padding: 14px 16px;
    text-decoration: none;
}

.dropdown {
    float: left;
    overflow: hidden;
}

.dropdown .dropbtn {
    font-size: 16px;    
    border: none;
    outline: none;
    color: white;
    padding: 14px 16px;
    background-color: inherit;
    font-family: inherit;
    margin: 0;
}

.navbar a:hover, .dropdown:hover .dropbtn {
    background-color: rgb(249, 197, 249);
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    z-index: 1;
}

.dropdown-content a {
    float: none;
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;
    text-align: left;
}

.dropdown-content a:hover {
    background-color: rgb(249, 197, 249);
}

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

标签： htmlcssnavigationpositionnavbar

解决方案

由于h1上面不需要的边距和标签，您有间距navbar

所以你需要从课堂上删除边距navbar并移到h1下面navbar

见下面的演示

h1 {
	font-size: 54px;
	font-family: 'Kalam', cursive;
	margin: 10px;
	color: #333;
}
body {
	background: url("flowers.jpg") no-repeat fixed;
margin: 0;
}


.navbar {
    overflow: hidden;
    background-color: #333;
    font-family: 'Poiret One', cursive;
	background-color: rgba(249, 197, 249, 0.5);
	width: 100%;
}

.navbar a {
    float: left;
    font-size: 16px;
    color: white;
    text-align: center;
    padding: 14px 16px;
    text-decoration: none;
}

.dropdown {
    float: left;
    overflow: hidden;
}

.dropdown .dropbtn {
    font-size: 16px;    
    border: none;
    outline: none;
    color: white;
    padding: 14px 16px;
    background-color: inherit;
    font-family: inherit;
    margin: 0;
}

.navbar a:hover, .dropdown:hover .dropbtn {
    background-color: rgb(249, 197, 249);
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    z-index: 1;
}

.dropdown-content a {
    float: none;
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;
    text-align: left;
}

.dropdown-content a:hover {
    background-color: rgb(249, 197, 249);
}

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