This article mainly introduces two pure CSS breadcrumb navigation bar implementation codes. The content is relatively simple. Friends who don’t know how to do it can come in and take a look. The HTML code implementation is very simple. Friends who need it can refer to it

Below are two pure CSS breadcrumb navigation bar implementation codes. I found some methods on the Internet but felt they were not suitable. Only these two pure CSS ones are almost the same. Let me sort it out for you. .

Method 1,

Description: This method uses CSS3, no pictures, and is compatible with various webkit browsers at the same time. First picture:

　1. First is the HTML code, which is relatively simple. It only requires a simple ul and li. The code is as follows:

<p id="crumbs">
<ul>
 <li><a href="#">首页</a></li>
 <li><a href="#">目录</a></li>
 <li><a href="#">子目录</a></li>
</ul>
<p class="fixed"></p>
</p>

2. Next is the CSS code. The first is to set the regular li floating and a tag beautification:

#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;
}

The next step is the key to breadcrumb navigation Place, create arrow effect through before and after:

#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;
}
