There is an IFRAME nested in the DIV, and the DIV at the bottom cannot be displayed_html/css_WEB-ITnose

I have a page frame that is exactly the same as this one (http://www.aa25.cn/layout/14.1-1-(1 3)-1/).
I have embedded an iframe on the right side of the main content. , then the footer DIV below cannot be displayed. . Don't know why. .

I hope you can give me some advice. .

I am a good poster here. Could it be? ? ?

Oh, you nested an iframe in the contentDIV in the address I gave above, and the footer below is still displayed? ?

I don’t have one.

This is the Header

This is the sidebar
