您需要做的就是使用伪元素的边框和定位来进行更多操作。像这样:
.block {
position: relative;
background: black;
height: 100px;
width: 100px;
border: 2px solid teal;
border-right: none;
}
.block::after{
content: '';
width: 100%;
height: 100%;
position: absolute;
background: inherit;
z-index: -1;
top: -2px;
right: -2px;
transform-origin: right bottom;
transform: skewX(-20deg);
border: 2px solid teal;
}
<div class="block"></div>
