这里是创建语音气泡的代码。您也可以更改变量和指针位置here

.speech-bubble {
    position: relative;
    background: #00aabb;
    border-radius: .4em;
}

.speech-bubble:after {
    content: '';
    position: absolute;
    bottom: 0;
    left: 50%;
    width: 0;
    height: 0;
    border: 30px solid transparent;
    border-top-color: #00aabb;
    border-bottom: 0;
    border-left: 0;
    margin-left: -15px;
    margin-bottom: -30px;
}

这个CSS应该让你开始,只是玩它:

#speech-bubble {
   width: 120px; 
   height: 80px; 
   background: blue;
   position: absolute;
   -moz-border-radius: 10px; 
   -webkit-border-radius: 10px; 
   border-radius: 10px;
}
#speech-bubble:before {
   content:"";
   position: absolute;
   width: 0;
   height: 0;
   border-top: 3px solid transparent;
   border-right: 26px solid blue;
   border-bottom: 23px solid transparent;
   margin: 13px 0 0 -25px;
}

这是JS Bin demo
