雪佛龙按钮

Question

我希望用CSS实现这一目标：

这就是我所拥有的：

＆＃13;

＆＃13;

.breadcrumb {
  list-style: none;
  overflow: hidden;
  font: 18px Helvetica, Arial, Sans-Serif;
  margin: 0;
  padding: 0;
}

.breadcrumb li {
  float: left;
}

.breadcrumb li a {
  border: 1px solid #c00;
  color: black;
  text-decoration: none;
  padding: 10px 0 10px 55px;
  background: #fff;
  position: relative;
  display: block;
  float: left;
}

.breadcrumb li a:after {
  content: " ";
  display: block;
  width: 0;
  height: 0;
  border-top: 50px solid transparent;
  /* Go big on the size, and let overflow hide */
  border-bottom: 50px solid transparent;
  border-left: 30px solid #fff;
  position: absolute;
  top: 50%;
  margin-top: -50px;
  left: 100%;
  z-index: 2;
}

.breadcrumb li a:before {
  content: " ";
  display: block;
  width: 0;
  height: 0;
  border-top: 50px solid transparent;
  /* Go big on the size, and let overflow hide */
  border-bottom: 50px solid transparent;
  border-left: 30px solid red;
  position: absolute;
  top: 50%;
  margin-top: -50px;
  margin-left: 1px;
  left: 100%;
  z-index: 1;
}

.breadcrumb li:first-child a {
  padding-left: 10px;
}

.breadcrumb li a:hover {
  background: hsla(34, 85%, 25%, 1);
}

.breadcrumb li a:hover:after {
  border-left-color: hsla(34, 85%, 25%, 1) !important;
}

.breadcrumb li:last-child a {
  border-right: 1px solid red;
}

.breadcrumb li:last-child a:before {
  border-left: 0 solid transparent;
}

＆＃13;

<ul class="breadcrumb">
  <li><a href="#">Home</a></li>
  <li><a href="#">Vehicles</a></li>
</ul>

＆＃13;

＆＃13;

＆＃13;

的问题：

1. 无法正确显示右侧边框
2. 不能让最后一个元素的右边界正常（不是雪佛龙）
3. 由于右侧边框，无法使悬停状态正确。

  text-decoration: none;
  padding: 10px 10px 10px 32px;
  position: relative;
  display: block;
  z-index: 99;
  font-weight: bold;
}
.breadcrumb li:first-child a {

  border-right: none;
}

.breadcrumb li:last-child a {
 border-left: none;
}
.breadcrumb li:before, .breadcrumb li:after{
  content: " "; 
  display: block; 
  width: 33px; 
  height: 29px; 
  border-top: 5px solid transparent; 
  border-bottom: 1px solid #0976a1; 
  border-right: 1px solid #0976a1; 
  position: absolute; 
  top: 4px; 
  z-index: -1;
  background: #fff;
  transform: rotate(-45deg);
  -moz-transform: rotate(-45deg);

}
.breadcrumb li:before {
  left: 87%; 
}
.breadcrumb li:after {
  left: 81%;
}
.breadcrumb li:first-child:before, .breadcrumb li:first-child:after{ z-index: 1; }
.breadcrumb li:first-child:after{ left: 73%; }
.breadcrumb li:last-child:before, .breadcrumb li:last-child:after{
  display: none;
}


.breadcrumb li:first-child:hover:after, .breadcrumb li:hover{ background: #0976a1; }
.breadcrumb li:hover a{ border-color: transparent; }
.breadcrumb li:hover a{ color: #fff; }

<ul class="breadcrumb">
  <li><a href="#">Home</a></li>
  <li><a href="#">Vehicles</a></li>
</ul>

我希望这会对你有所帮助:)。

*{
  margin: 0;
  padding: 0;
}
.container{
  margin: 20px;
  display: flex;
  flex-direction: row;
  border: 1px solid skyblue;
  width: 200px;
  overflow: hidden;
}


.left,.right{
  display: inline-block;
  //border: 1px solid black;
  line-height: 50px;
  width: 100px;
  height: 100%;
  position: relative;

  
}

.right{
    text-align: center;
}
p:hover{
  background-color: skyblue;
  color: white;
}
.left::after{
  content:'';
  position: absolute;
  left: 70px;
  top: 3px;
  display: inline-block;
  width: 45px;
  height: 45px;
  z-index: 2;
  background:white;
  transform:rotate(-45deg);
  border-right: 1px solid skyblue;
  border-bottom: 1px solid skyblue;
  
}
.left:hover::after{
  background-color: skyblue;
}

<div class="container">
  <p class="left">LEFT</p>
  <p class="right">RIGHT</p>
</div>

这是我的最佳状态。

我希望它对你有用。
