css - 跨越整个导航栏的下拉菜单

问题描述

好的，所以我正在上一个 Web 开发课程，我目前正在处理该课程的最后一个项目。我决定要在导航栏中有一个下拉菜单，所以我按照 w3schools 教程进行操作，但有一个小问题。下拉菜单虽然看起来不错，但似乎已经决定它的背景跨越整个导航栏听起来像是一个伟大的想法。这是它的外观

你们中的任何人都知道如何解决这个问题吗？这是我的代码

.menu{
	overflow: hidden;
	background-color: #000;
	max-width: 100%;
	position:relative;
	top: -120px;
	font-size: 16px;
}
.menu a{
	float: left;
	display: block;
	color: white;
	text-align: center;
	padding: 14px 20px;
	text-decoration: none;
}
.menu a:link
.menu a:visited{
	text-decoration: none;
}
.active{
	background-color: #C00;
}
.dropdown{
	float: left;
	overflow: hidden;
}
.dropdown .dopbtn{
	font-size: 16px;
	border: none;
	outline: none;
	color: white;
	padding: 14px 16px;
	background-color: inherit;
	font-family: inherit;
	margin: 0;
}
.menu a:hover, .dropdown:hover .dropbtn{
	background-color: #9B0000;
}
.dropdown-content{
	display: none;
	position: static;
	background-color: black;
	max-width: 160px;
	box-shadow: 0px 8px 16px 0px grey;
	z-index: 1;
}
.dropdown-content a{
	float: left;
	color: white;
	padding: 12px 16px;
	text-decoration: none;
	display: block;
	text-align: left;
}
.dropdown-content a:hover{
	background-color: #7B0002;
}
.dropdown:hover .dropdown-content{
	display: block;
}
