可以使用 CSS 创建以下边框模式吗?
It is possible to use CSS to create the following border pattern?
我想添加如下边框图案:
div {
border: 1px solid #ddd;
position: relative;
height: 150px;
text-align: center;
margin-top: 3em;
}
ul {
padding: 0;
position: absolute;
top: -55px;
left: 0;
right: 0;
}
li {
display: inline-block;
}
h3 {
background: #fff;
padding: 10px 20px;
border-top: 1px solid #dadada;
border-bottom: 1px solid #dadada;
}
<div>
<ul>
<li><h3>Test</h3><span>Test<br/>Test<br/>Test</span></li>
<li><h3>Test</h3><span>Test<br/>Test<br/>Test</span></li>
<li><h3>Test</h3><span>Test<br/>Test<br/>Test</span></li>
<li><h3>Test</h3><span>Test<br/>Test<br/>Test</span></li>
</ul>
</div>
是否可以用纯 CSS 创建此边框图案?
使用 Pure CSS 是可能的,您必须尝试使用如下形状:https://css-tricks.com/examples/ShapesOfCSS/
另一个简单的选择是将这些箭头的图像作为 :before 和 :after
这里有一些代码可以为您说明一种可能的方法(虽然略有不同):

<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>
