如何用css制作圆形标签？

Question

我想知道是否可以使用CSS存档以下效果

我发现这些文章有点帮助但问题是在我的情况下标签边是对角线而不是直线垂直线:

这是纯CSS的概念验证示例.它使用伪元素和rotate.它与您的源图像非常接近,可能会与某些工作更接近.

HTML:

<ul>
    <li>Sample 1</li>
    <li class="active">Sample 2</li>
    <li>Sample 3</li>
    <li>Sample 4</li>
</ul>

CSS:

/* Reset ul styles */
body { font-family: sans-serif; }
ul {
    list-style: none;
    margin: 0;
    padding: 0;
}

ul {
    padding-left: 20px;
    z-index: 5;
}
ul li {
    color: grey;
    background: #fefefe;
    padding: 14px 24px 10px;
    margin: 0px -6px 0 10px;
    position: relative;
    float: left;
    text-align: center;
    z-index: 1;
}
ul li::before {
    content: '';
    display: block;
    position: absolute;
    top: 0; left: 0;
    width: 70%;
    height: 100%;
    border-style: solid;
    border-color: #eee;
    border-width: 2px 0 2px 2px;
    border-radius: 8px 0 0 0;
    -webkit-transform: skewX(-20deg);
       -moz-transform: skewX(-20deg);
         -o-transform: skewX(-20deg);
            transform: skewX(-20deg);
    background-color: inherit;
    z-index: -1;
}
ul li::after {
    content: '';
    display: block;
    position: absolute;
    top: 0; right: 0;
    width: 70%;
    height: 100%;
    border-style: solid;
    border-color: #eee;
    border-width: 2px 2px 2px 0;
    border-radius: 0 8px 0 0;
    -webkit-transform: skewX(20deg);
       -moz-transform: skewX(20deg);
         -o-transform: skewX(20deg);
            transform: skewX(20deg);
    background-color: inherit;
    z-index: -1;
}
ul li.active {
    color: orange;
    z-index: 10;
}
ul li.active::before,
ul li.active::after {
    background-color: #fff;
    border-bottom-color: #fff;
}
ul li:not([class='active']):hover::before,
ul li:not([class='active']):hover::after {
    background-color: #efefef; 
}
