CSS 面包屑導航欄2個例子
方法一，
說明：本方法使用CSS3，無圖片，兼容各種webkit系浏覽器，同時兼容IE8+。先上圖：
1.首先是HTML代碼，比較簡單，只需要一個簡單的ul和li即可
代碼如下<div id="crumbs">
<ul>
<li><a href="#">首頁</a></li>
<li><a href="#">目錄</a></li>
<li><a href="#">子目錄</a></li>
</ul>
<div class="fixed"></div>
</div>
2.接下來是CSS代碼，首先是設定常規的li浮動和a標簽美化：
代碼如下#crumbs ul li {
float: left;
list-style: none;
}
#crumbs ul li a {
display: block;
float: left;
height: 34px;
background: #f66fa2;
text-align: center;
padding: 10px 20px 0 45px;
position: relative;
margin: 0 10px 0 0;
font-size: 20px;
text-decoration: none;
color: #fff;
}
接下來就是面包屑導航的關鍵地方，通過before和after來創建箭頭效果：
代碼如下#crumbs ul li a:after {
content: "";
border-top: 22px solid transparent;
border-bottom: 22px solid transparent;
border-left: 22px solid #f66fa2;
position: absolute; right: -22px; top: 0;
z-index: 1;
}
#crumbs ul li a:before {
content: "";
border-top: 22px solid transparent;
border-bottom: 22px solid transparent;
border-left: 22px solid #fff;
position: absolute; left: 0; top: 0;
}
#crumbs ul li:first-child a {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
padding-left: 40px;
}
#crumbs ul li:first-child a:before {
display: none;
}
#crumbs ul li:last-child a {
padding-right: 30px;
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
#crumbs ul li:last-child a:after {
display: none;
}
#crumbs ul li a:hover {
background: #e56592;
transition: all 0.2s ease;
}
#crumbs ul li a:hover:after {
border-left-color: #e56592;
transition: all 0.2s ease;
}
最後清除浮動：
代碼如下.fixed {
clear: both;
}
方法二
代碼如下<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset="utf-8″ />
