第一我们来看一下我们需要制作的对话框的结果

代码如下

HTML代码

左边

CSS代码

 .balloon-left {
  position: relative;
  display: inline-block;
  padding: 0 15px;
  width: auto;
  min-width: 150px;
  height: 40px;
  line-height: 34px;
  text-align: center;
  background: #44FF44;
  border: 3px solid #000000;

CSS代码

.balloon-left:before {
  border-style: solid;
  border-width: 10px 10px 10px 0;
  border-color: transparent #44FF44 transparent transparent;
  content: "";
  position: absolute;
  top: 50%; left: -8px;
  margin-top: -9px;
  display: block;
  width: 0px;
  height: 0px;
  z-index: 0;
}
.balloon-left:after {
  border-style: solid;
  border-width: 11px 11px 11px 0;
  border-color: transparent #000000 transparent transparent;
  content: "";
  position: absolute;
  top: 50%; left: -12px;
  margin-top: -10px;
  display: block;
  width: 0px;
  height: 0px;
  z-index: -1;
