从右到左更改背景div颜色指示器方向

Question

我正在努力改变这个“右上角”＆＃39;左上角的指示符＆＃39;指示符。

＆＃13;

＆＃13;

.right {
  position: relative;
  background: aqua;
  text-align: right;
  min-width: 45%;
  padding: 10px 15px;
  border-radius: 6px;
  border: 1px solid #ccc;
  float: right;
  right: 20px;
}

.right::before {
  content: '';
  position: absolute;
  visibility: visible;
  top: -1px;
  right: -10px;
  border: 10px solid transparent;
  border-top: 10px solid #ccc;
}

.right::after {
  content: '';
  position: absolute;
  visibility: visible;
  top: 0px;
  right: -8px;
  border: 10px solid transparent;
  border-top: 10px solid aqua;
  clear: both;
}

＆＃13;

Answer 1

只需在选择器之前和之后从右向左更改。

.right {
  position: relative;
  background: aqua;
  text-align: right;
  min-width: 45%;
  padding: 10px 15px;
  border-radius: 6px;
  border: 1px solid #ccc;
  float: right;
  right: 20px;
}

.right::before {
  content: '';
  position: absolute;
  visibility: visible;
  top: -1px;
  left: -10px;
  border: 10px solid transparent;
  border-top: 10px solid #ccc;
}

.right::after {
  content: '';
  position: absolute;
  visibility: visible;
  top: 0px;
  left: -8px;
  border: 10px solid transparent;
  border-top: 10px solid aqua;
  clear: both;
}

<div class="right">
  <span>thanks</span>
</div>

简单，只需用right替换left的所有实例？

.left {
  position: relative;
  background: aqua;
  text-align: left;
  min-width: 45%;
  padding: 10px 15px;
  border-radius: 6px;
  border: 1px solid #ccc;
  float: left;
  left: 20px;
}

.left::before {
  content: '';
  position: absolute;
  visibility: visible;
  top: -1px;
  left: -10px;
  border: 10px solid transparent;
  border-top: 10px solid #ccc;
}

.left::after {
  content: '';
  position: absolute;
  visibility: visible;
  top: 0px;
  left: -8px;
  border: 10px solid transparent;
  border-top: 10px solid aqua;
  clear: both;
}

<div class="left">
  <span>thanks</span>
</div>
