1. 内联列表实现
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>hello world</title>
<style>
ul
{
/* 不显示列表前的标记 */
list-style-type:none;
margin:0;
padding:0;
}
li
{
/* 将块元素转变为内联元素 */
display:inline;
}
</style>
</head>
<body>
<ul>
<li><a href="#home">主页</a></li>
<li><a href="#news">新闻</a></li>
<li><a href="#contact">联系</a></li>
<li><a href="#about">关于</a></li>
</ul>
</body>
</html>

2. 浮动列表实现
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>hello world </title>
<style>
ul
{
list-style-type:none;
margin:0;
padding:0;
overflow:hidden;
}
li
{
float:left;
}
a
{
display:block;
padding: 14px 16px;
text-decoration: none;
}
</style>
</head>
<body>
<ul>
<li><a href="#home">主页</a></li>
<li><a href="#news">新闻</a></li>
<li><a href="#contact">联系</a></li>
<li><a href="#about">关于</a></li>
</ul>

3. 添加边框
3.1 思路
- 添加整体边框
ul {
……
background-color: #333;
}
- 给主页添加一个不同的效果
.active {
background-color: #4CAF50;
}
- 添加鼠标悬停效果，排除首页
li a:hover:not(.active) {
background-color: #aaaaaa;
}
3.2 实际效果
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>hello world</title>
<style>
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}
li a:hover:not(.active) {
background-color: #aaaaaa;
}
.active {
background-color: #4CAF50;
}
</style>
</head>
<body>
<ul>
<li><a class="active" href="#home">主页</a></li>
<li><a href="#news">新闻</a></li>
<li><a href="#contact">联系</a></li>
<li><a href="#about">关于</a></li>
</ul>
</body>
</html>

4. 添加分割线
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>hello world</title>
<style>
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
/* 右侧添加一个边框 */
border-right:1px solid #bbb;
}
/* 最后一个li不添加右边框 */
li:last-child {
border-right: none;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}
li a:hover:not(.active) {
background-color: #dddddd;
}
.active {
background-color: #4CAF50;
}
</style>
</head>
<body>
<ul>
<li><a class="active" href="#home">主页</a></li>
<li><a href="#news">新闻</a></li>
<li><a href="#contact">联系</a></li>
