I know there are many differences between IE and FF (firefox), but I am not asking about all of them.

I am making a new skin for a site, to look at the old skin, follow this link:

http://www.kirken-aalesund.no/Default.aspx?alias=www.kirken-aalesund.no/spjelkavik

Why is the border around the content showing different in the two browsers? IE shows the same color as the top panel and FF shows a blue border. Both browsers showed the blue border until my host told me to add the code  .skinmaster {border:2px solid cacaae} to portal.css. Why doesn't FF read this code?

All the fonts shows different in FF and IE (it looks best in IE, and it is closest to what we want). It seems to me that FF does not read some of the css (in one or more of the css files). (I won't even mention the search-boks appearance in FF). Why is this happening?

Thanks, that # solved the border issue in FF.

So maybe the rest of the differences also boils down to sloppy css-writing?

My problem is that I am only a user that administrate the site. What css-styles our web-host writes i cannot control. When making my skin I must be careful not to override any css-style from my host that have to be there to use the modules properly.
