通过CSS写提示工具栏的上下左右箭头

背景：现在很多提示工具栏都是组件库自带的，但是有些项目是通过原生js+jquery写的。这种项目就需要自己去写样式了

话不多说直接上代码：
1，剪头向下的

<!DOCTYPE html>
<html>
<style>
.tooltip {
  position: relative;
  display: inline-block;
  border-bottom: 1px dotted black;
}

.tooltip .tooltiptext {
  visibility: hidden;
  width: 120px;
  background-color: black;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 5px 0;
  position: absolute;
  z-index: 1;
  top: 150%;
  left: 50%;
  margin-left: -60px;
}

.tooltip .tooltiptext::after {
  content: "";
  position: absolute;
  bottom: 100%;
  left: 50%;
  margin-left: -5px;
  border-width: 5px;
  border-style: solid;
  border-color: black transparent transparent transparent;
}

.tooltip:hover .tooltiptext {
  visibility: visible;
}
</style>
<body style="text-align:center;">

<h1>下方工具提示 w/ 上箭头</h1>

<div class="tooltip">Hover over me
  <span class="tooltiptext">Tooltip text</span>
</div>

</body>
</html>

2，剪头朝上

.tooltip .tooltiptext::after {
  content: " ";
  position: absolute;
  bottom: 100%;  /* At the top of the tooltip */
  left: 50%;
  margin-left: -5px;
  border-width: 5px;
  border-style: solid;
  border-color: transparent transparent black transparent;
}

3，剪头向右

.tooltip .tooltiptext::after {
  content: " ";
  position: absolute;
  top: 50%;
  left: 100%; /* To the right of the tooltip */
  margin-top: -5px;
  border-width: 5px;
  border-style: solid;
  border-color: transparent transparent transparent black;
}

4，剪头向左

.tooltip .tooltiptext::after {
  content: " ";
  position: absolute;
  top: 50%;
  right: 100%; /* To the left of the tooltip */
  margin-top: -5px;
  border-width: 5px;
  border-style: solid;
  border-color: transparent black transparent transparent;
}
