It worked after I fixed these problems, but now I have the problem that the text from the object cannot be styled from outside.
Is that a problem? I suppose it could be styled from the inside. The style of the menu bar seems to be defined between <STYLE> tags on the pages itself (line 21-69 for the page I am looking at), rather than from an external CSS file. These lines could be just as well in the external file included by the <object>. If they are always the same, one could argue it is even better to have them there, as this external file is supposed to be cached.
I admit that I am puzzled by the fact that the browser tries to keep the styles separate, but perhaps that also means that the main page and the external html can each link to their own CSS file, without the styles interfering with each other.
