CSS自定义标签形状 - 额外的线条

Question

请参阅此链接。https://codepen.io/wbeeftink/pen/dIaDH。如果缩小或放大，您会看到标签底部有一条额外的线条。请参阅屏幕截图。

有人可以告诉我这是如何解决的。或者有不同的方法来创建这样的标签？ 这是我使用的代码

HTML

<span class="tag">HTML</span>

CSS

.tag {
  background: #eee;
  border-radius: 3px 0 0 3px;
  color: #999;
  display: inline-block;
  height: 26px;
  line-height: 26px;
  padding: 0 20px 0 23px;
  position: relative;
  margin: 0 10px 10px 0;
  text-decoration: none;
  -webkit-transition: color 0.2s;
}

.tag::before {
  background: #fff;
  border-radius: 10px;
  box-shadow: inset 0 1px rgba(0, 0, 0, 0.25);
  content: '';
  height: 6px;
  left: 10px;
  position: absolute;
  width: 6px;
  top: 10px;
}

.tag::after {
  background: #fff;
  border-bottom: 13px solid transparent;
  border-left: 10px solid #eee;
  border-top: 13px solid transparent;
  content: '';
  position: absolute;
  right: 0;
  top: 0;
}

Answer 1

将.tag::after的样式从right: 0更改为left: 100%。

body {
  font: 12px/1.5 'PT Sans', serif;
  margin: 25px;
}

.tags {
  list-style: none;
  margin: 0;
  overflow: hidden; 
  padding: 0;
}

.tags li {
  float: left; 
}

.tag {
  background: #eee;
  border-radius: 3px 0 0 3px;
  color: #999;
  display: inline-block;
  height: 26px;
  line-height: 26px;
  padding: 0 20px 0 23px;
  position: relative;
  margin: 0 10px 10px 0;
  text-decoration: none;
  -webkit-transition: color 0.2s;
}

.tag::before {
  background: #fff;
  border-radius: 10px;
  box-shadow: inset 0 1px rgba(0, 0, 0, 0.25);
  content: '';
  height: 6px;
  left: 10px;
  position: absolute;
  width: 6px;
  top: 10px;
}

.tag::after {
  background: #fff;
  border-bottom: 13px solid transparent;
  border-left: 10px solid #eee;
  border-top: 13px solid transparent;
  content: '';
  position: absolute;
  left: 100%;
  top: 0;
}

.tag:hover {
  background-color: crimson;
  color: white;
}

.tag:hover::after {
   border-left-color: crimson; 
}
