关于iframe的透明背景

注重以下效果必需IE5.5以上版本才支持

　　在transparentBody.htm文件的%26lt;body%26gt;标签中，我已经加入了style="background-color=transparent" 通过以下四种IFRAME的写法我想大概你对iframe背景透明效果的实现方法应该会有个清楚的了解
%26lt;IFRAME ID="Frame1" SRC="transparentBody.htm" allowTransparency="true"%26gt;%26lt;/IFRAME%26gt;

%26lt;IFRAME ID="Frame2" SRC="transparentBody.htm" allowTransparency="true" STYLE="background-color: green"%26gt; %26lt;/IFRAME%26gt;

%26lt;IFRAME ID="Frame3" SRC="transparentBody.htm"%26gt;%26lt;/IFRAME%26gt;

%26lt;IFRAME ID="Frame4" SRC="transparentBody.htm" STYLE="background-color: green"%26gt; %26lt;/IFRAME%26gt;
