IE6下PNG图片透明服务器端解决办法

使用iepngfix.htc文件解决png图片在IE6下不透明的问题。

什么是htc文件?

从5.5版本开始,Internet Explorer(IE)开始支持Web 行为的概念。这些行为是由后缀名为.htc的脚本文件描述的,它们定义了一套方法和属性,程序员几乎可以把这些方法和属性应用到HTML页面上的任何元素上去。Web 行为是非常伟大的因为它们允许程序员把自定义的功能“连接”到现有的元素和控件,而不是必须让用户下载二进制文件(例如ActiveX 控件)来完成这个功能。Web 行为还是推荐的扩展IE对象模型和控件集的方法。 更多介绍

一点介绍:

This is a IE5.5+ “behavior” that automatically adds near-native PNG support to MSIE 5.5 and 6.0 without any changes to the HTML document itself. Supported features include:

  • Automatic activation of transparency for PNGs in the page.
  • Support for <IMG SRC=””> elements.
  • Support for background PNG images (unlike many other scripts!)
  • Support for CSS1 background repeat and position (via optional add-on)
  • Background images can be defined inline or in external stylesheets.
  • Automatically handles changed SRC/background via normal JavaScript  (e.g. mouseover rollovers) — no special coding needed.
  • Change support includes CSS ‘className’ changes on elements.
  • Incorporates automatic workaround for <a href=””> elements within  PNG-background elements.
  • Tiny script (for fast downloads).
