Made a breadcrumb navigation based on the tutorial. I will share the implementation method here and review it myself. The first effect is as shown below:

The HTML code is as follows:

<div id="crumbs">	<ul>		<li><a href="#">Breadcrumb</a></li>	</ul></div>我们用一个无序列表来填充面包屑导航。每一个导航连接都相当于一个内嵌了<a>元素的<li>元素。首先将每一个a元素渲染为蓝色的矩形框。文本居中放置,两边加上适当的内边距。设置<a>元素为相对定位。这样它的绝对定位的子元素可以相对于它来进行定位。

#crumbs ul li a {	display: block;	float: left;	height: 50px;	background: #3498db;	text-align: center;	padding: 30px 40px 0 40px;	position: relative;	margin: 0 10px 0 0; 		font-size: 20px;	text-decoration: none;	color: #fff;}
Copy after login

使用:after选择器创建一个元素。使用css边框来生成一个三角形。给使用:after选择器生成的元素应用上下边框,左边框,然后把上下边框的颜色设置成透明的。在将该元素放置到合适的地方(通过position:absolute),注意设置z-index

#crumbs ul li a:after {	content: "";  	border-top: 40px solid red;	border-bottom: 40px solid red;	border-left: 40px solid blue;	position: absolute; right: -40px; top: 0;        z-index:5;}

设置上下边框为透明,重新设置左边框的颜色后

border-top: 40px solid transparent;border-bottom: 40px solid transparent;border-left: 40px solid #3498db;
Copy after login

使用同样的方法,在矩形框的左边渲染一个三角形样式。这一次还是设置:before元素的上下边框为透明,设置左边框的颜色和页面的背景色一致,伪装成页面的一部分
Copy after login
#crumbs ul li a:before {	content: "";  	border-top: 40px solid transparent;	border-bottom: 40px solid transparent;	border-left: 40px solid #d4f2ff;	position: absolute; left: 0; top: 0;}
Copy after login

<div id="crumbs">	<ul>		<li><a href="#1">One</a></li>		<li><a href="#2">Two</a></li>		<li><a href="#3">Three</a></li>		<li><a href="#4">Four</a></li>		<li><a href="#5">Five</a></li>	</ul></div>
Copy after login

#crumbs ul li:first-child a {	border-top-left-radius: 10px; border-bottom-left-radius: 10px;}#crumbs ul li:first-child a:before {	display: none; }#crumbs ul li:last-child a {	padding-right: 80px;	border-top-right-radius: 10px; border-bottom-right-radius: 10px;}#crumbs ul li:last-child a:after {	display: none; }
Copy after login
#crumbs ul li a:hover {	background: #fa5ba5;}	#crumbs ul li a:hover:after {		border-left-color: #fa5ba5;	}此次一个完整的面包屑导航就完成了。翻译水平还是有待提升。。。附上原文地址:http://line25.com/tutorials/how-to-create-flat-style-breadcrumb-links-with-css
