如何为椭圆左侧应用 CSS 边框颜色？

Question

我试图只在椭圆的左侧应用白色边框，而将其他边保持为 transparent.However，边框没有应用到左侧的整个部分 side.What需要更改才能显示预期的输出？

#ellipsis {
  background-color: #3ebede;
  height: 25px;
  color: #000;
  position: relative;
  padding: 4px 15px 4px 30px;
  width: 200px;
  border-radius: 20px;
  margin: -4px -25px -4px -4px;
  text-align: left;
  display: inline-block;
  border: solid;
  border-color: transparent transparent transparent white
}

<body>
  <button id="ellipsis"></button>
  <button id="ellipsis"></button>
  <button id="ellipsis"></button>

</body>

改为考虑 box-shadow：

.ellipsis {
  background-color: #3ebede;
  height: 25px;
  color: #000;
  position: relative;
  padding: 4px 15px 4px 30px;
  width: 200px;
  border-radius: 20px;
  margin: -4px -25px -4px -4px;
  text-align: left;
  display: inline-block;
  box-shadow:-2px 0 0 2px #fff;
  border:none;
}

<body>
  <button class="ellipsis"></button>
  <button class="ellipsis"></button>
  <button class="ellipsis"></button>

</body>

如果你想要透明度，这里有一个技巧 radial-gradient:

.ellipsis {
  background-color: #3ebede;
  height: 25px;
  color: #000;
  position: relative;
  padding: 4px 15px 4px 30px;
  width: 200px;
  border-radius: 20px;
  margin: -4px -25px -4px -4px;
  text-align: left;
  display: inline-block;
  border:none;
}
.ellipsis:not(:last-child) {
  background:radial-gradient(4px 3px at right,transparent 30px,#3ebede 31px); 
}

body {
  background:#ddd;
}

<div>
  <button class="ellipsis"></button>
  <button class="ellipsis"></button>
  <button class="ellipsis"></button>

</div>
