三角形翻转的效果，大家想必见过，这里就把相关代码贴下，大家可以应用哦，当然翻转效果暂时不支持IE 6 7 8。

1、纯CSS做个三角

代码如下：
<style type="text/css">
.rightdirection
{
width:0;height:0;
line-height:0;
border-width:20px;
border-style:solid;
border-color:transparent transparent transparent #A9DBF6;
}
.bottomdirection
{
width:0;height:0;
line-height:0;
border-width:20px;
border-style:solid;
border-color: #A9DBF6 transparent transparent transparent;
}
.leftdirection
{
width:0;height:0;
line-height:0;
border-width:20px;
border-style:solid;
border-color: transparent #A9DBF6 transparent transparent;
}
.topdirection
{
width:0;height:0;
line-height:0;
border-width:20px;
border-style:solid;
border-color: transparent transparent #A9DBF6 transparent;
}
</style>
<div class="rightdirection"></div>
<p>
<div class="bottomdirection"></div>
<p>
<div class="leftdirection"></div>
<p>
<div class="topdirection"></div>

2.翻转：实现翻转

<!DOCTYPE html>
<html>
<head>
<style>

.jt b {
    border-color: #FFD0C0 rgba(0, 0, 0, 0) rgba(0, 0, 0, 0);
    border-style: solid dashed dashed;
    border-width: 10px;
    font-size: 0;
    height: 0;
    line-height: 0;
    position: absolute;
    left: 150px;
    top: 14px;
    width: 0;
}
.jt:hover b {
    border-color: #ccc rgba(0, 0, 0, 0) rgba(0, 0, 0, 0);
    transform: rotate(180deg);
    transform-origin: 50% 30% 0;
    transition: transform 0.2s ease-in 0s;
-moz-transform: rotate(180deg);
    -moz-transform-origin: 50% 30% 0;
    -moz-transition: transform 0.2s ease-in 0s;
}
