Pure CSS to implement breadcrumb navigation_html/css_WEB-ITnose
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;}
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;
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
#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;}
<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>
#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; }
#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
