第一种方法：主要是通过css border属性来实现，两个小三角形叠加，实现小箭头；
代码如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<style type="text/css">
*{ margin:0; padding:0;}
body{ padding:20px; }
.tips{ background:#FFF8E8; border:1px solid #FFBA00; padding:10px; position:absolute;}
.trangle1{border-left:5px dashed transparent;border-right:5px dashed transparent;border-bottom:5px solid #FFBA00;width:0;height:0;font-size:0; position:absolute; top:-6px; left:29px;}
.trangle2{border-left:5px dashed transparent;border-right:5px dashed transparent;border-bottom:5px solid #FFF8E8;width:0;height:0;font-size:0; position:absolute; top:1px; left:-5px;}
</style>
</head>
<body>
<div class="tips">
<p> CSS实现Bubble提示框的方法</p>
<div class="trangle1">
<div class="trangle2"></div>
</div>
</div>
</body>
</html>
预览效果如下在ie中测试的：
第二种方法；主要是参考sofish的解决方法：主要是利用css3的transform方法和filter的一些兼容方法；

body{padding:20px;font:16px/1.5 Georgia;}
.diamond{
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(M11=0.7071067811865475, M12=-0.7071067811865477, M21=0.7071067811865477, M22=0.7071067811865475, SizingMethod='auto expand')";
filter: progid:DXImageTransform.Microsoft.Matrix(
M11=0.7071067811865475,
M12=-0.7071067811865477,
M21=0.7071067811865477,
M22=0.7071067811865475,
SizingMethod='auto expand'
);
-moz-transform: rotate(45deg);
-o-transform: rotate(45deg);
-webkit-transform: rotate(45deg);
-ms-transform: rotate(45deg);
transform:rotate(45deg);
}
:root .diamond{filter:none\9;}
.tips{position:absolute;background: #fff8e8;border:1px solid #ffba00;padding:10px;}
.tips-angle{position:absolute;display:block;width:8px;height:8px;font-size:0;background:#fff8ef;border-left:1px solid #ffba00;border-top:1px solid #ffba00;top:-5px;top:-6px\9;left:10px;}
