您可以简单地使用伪元素和一些border属性,然后调整不同的值以获得您想要的:
.link {
padding: 10px;
display: inline-block;
width: 80px;
border-top: 1px solid #000;
border-bottom: 1px solid #000;
text-align: center;
position: relative;
overflow: hidden;
}
.link:before,.link:after {
content: "";
position: absolute;
height: 30px;
width: 30px;
border: 1px solid #000;
left: -19px;
top: 3px;
background: #fff;
transform: rotate(45deg);
transform-origin: center;
}
.link:after {
right: -19px;
left:auto;
}
<a href="#" class="link">link</a>
