最近打算折腾一下网站的问答分类,所以在网上找了一个css实现对话框的效果,具体效果如下图:

CSS代码
#talk {
   margin-left: 50px;
   width: 220px;
   height: 60px;
   background: #9EEA6A;
   position: relative;
   -moz-border-radius:    10px;
   -webkit-border-radius: 10px;
   border-radius:         10px;
}
#talk:before {
   content:"";
   position: absolute;
   right: 100%;
   top: 16px;
   width: 0;
   height: 0;
   border-top: 13px solid transparent;
   border-right: 26px solid #9EEA6A;
   border-bottom: 13px solid transparent;
}
#talk2 {
   *margin-left: 50px;
   float:right;
   width: 220px;
   height: 60px;
   background: #9EEA6A;
   position: relative;
   -moz-border-radius:    10px;
   -webkit-border-radius: 10px;
   border-radius:         10px;
}
#talk2:before {
   content:"";
   position: absolute;
   left: 100%;
   top: 16px;
   width: 0;
   height: 0;
   border-top: 13px solid transparent;
   border-left: 26px solid #9EEA6A;
   border-bottom: 13px solid transparent;
}html代码
可以写个简单的html查看一下具体效果
<html>
	<div id="talk"></div>
	<div id="talk2"></div>
