ie6无法显示背景图(怎么把图片抠成透明背景png)

这种方法总是在开发项目时使用，它可以在两个简单的步骤中使用。

首先，在head和/head之间添加以下代码：

!--[if IE 6]

script src='png.js'/script

script

DD_belatedPNG.fix('.png_bg,img,b');

/script

![endif]--

png.js的完整代码如下：

/**

* DD_belatedPNG: Adds IE6 support: PNG images for CSS background-image and HTML IMG/.

* Author: Drew Diller

* Example usage:

* DD_belatedPNG.fix('.png_bg'); //argument is a CSS selector

* DD_belatedPNG.fixPng( someNode ); //argument is an HTMLDomElement

然后在需要使PNG透明的html代码中调用以下代码：

class='png_bg'
