Problems with CSS

[Bubu]

The code is ugly and perverse. Think of what you're really trying to
achieve here, then find a better way to do it. Gratuitous use of
absolute and hard-coded positioning is rarely indicative of a good
technical design.

<iframe> has limited uses, very few uses that would be appropriate when
XHTML is also appropriate, and it's certainly not a feature to be
recommended for purely presentation reasons.

My is not a web site, it's an interface for an electrnoic device that
need to be interfaced with other electronic devise via PHP, XML and
JavaScript.

iFrame is the solution choosed from the developer team, I need only to
know if exist a workaround for IE7.
The page uploaded is only an example, is not my page.
I have write down this test only to clarify the problem.
If you like you can put the css external but the problem is the same.

So, anyone has a trick, a workaround or a solution?

Thanks
