最初に、これが意味をなさない場合はお詫び申し上げます。XHTML、CSS、JavaScript は初めてです。
XHTML で、ネストされたページを作成する正しい方法は次のとおりです (iframe の代わりに)。
<object name="nestedPage" data="http://abc.com/page.html" type="text/html"
width="500" height="400" />
If I have a nested page like that - is it possible to change the stylesheet used by the nested page at runtime using JavaScript in the parent page? Ideally this would happen immediately so that the nested page would never be visible with its original stylesheet.
Please assume that you do not have control of the original source code of the nested page, yet it is on the same domain (don't ask)
