在此基础上，今天分享一篇文章给大家，如果利用CSS制作冒泡提示框。

CSS：

/*
     对话气泡
     用法：使用.speech-bubble和.speech-bubble-DIRECTION类
     <div class="speech-bubble speech-bubble-top">Hi there</div>
    */
     
    .speech-bubble {
      position: relative;
      background-color: #292929;
     
      width: 200px;
      height: 150px;
      line-height: 150px; /* 垂直居中 */
      color: white;
      text-align: center;
      border-radius: 10px;
      font-family: sans-serif;
    }
     
    .speech-bubble:after {
      content: '';
      position: absolute;
     
      width: 0;
      height: 0;
     
      border: 15px solid;
    }
     
    /* 箭头的位置 */
    .speech-bubble-top:after {
      border-bottom-color: #292929;
      left: 50%;
      bottom: 100%;
      margin-left: -15px;  
    }
    .speech-bubble-right:after {
      border-left-color: #292929;
     
      left: 100%;
      top: 50%;
      margin-top: -15px;   
    }
     
    .speech-bubble-bottom:after {
      border-top-color: #292929;
      top: 100%;
      left: 50%;
      margin-left: -15px;  
    }
     
    .speech-bubble-left:after {
      border-right-color: #292929;
      top: 50%;
      right: 100%;
      margin-top: -15px;   
    }

            <div class="speech-bubble speech-bubble-bottom">

            </div>
            <br/>
            <div class="speech-bubble speech-bubble-left">
