I am working on a Joomla 1.5 website and a little self-contained php application, which I want to show within an IFRAME inserted in an article. The template I am using for the website has a dark grey background and the IFRAME shows grey background when loaded in Firefox (I don’t quite know why this is so, but I like it like this). However, when the page is loaded in IE, the IFRAME has white background (understandably).

How can I make the IFRAME copy the background color of its parent document also in IE?

Also, I have another unanswered question related to IFRAME usage and Joomla 1.5, which I would like to point your attention to.

    If the self-contained application is on the same domain as the article page, you could access the top frame (with the article) through javascript – like this:

    document.body.style.backgroundColor = getComputedStyle(window.top.document.body);

    Computed style can be get as described in this article.

    Your other option is to add a query string parameter for the iframe, like bgcolor= – this is a more widget-like approach, and will make the stand-alone application more configurable. I personally recommend this approach – it will not rely on javascript and it will not flicker if the execution gets slow.
