Button like Link :: Negative margin in IE

Hi guys,

I'm having a big problem doing something so simple it's not even funny.
i'd like to have a kind of button layout for my links.
What i want to achieve is exactly what you can see with FIREFOX on that
page : http://www.weloveindustry.fr/test.html

I'm struggling for hours now has i tried everything from divs, conainer,
simple a tags.

The two buttons are identical in shape and function but the css' i used
to create them are quite different.

Anyway, in both cases, under IE nothing is working : When I use padding
to have the right height on the first aptempt, ie pads around the arrow
where Firefox doesn't

And on the second attempt, IE does not seem to understand negative padding.

For one of the other is there a way to have consistency?

Thanks.

Can someone tell me what i did or say wrong, that nobody would take a
look at my problem ?

I fell a little left alone here

Regards.

Yahel
