Argh, CSS problem?

[nets]

In my CSS I have :

body
{margin-top:0;
margin-left:0;
margin-right:0;
margin-bottom:0;
}

I want to have no margins, this works fine in Firefox and Internet Explorer but when I use Opera browser it seems to still have the margins. Anyone know how to fix this?

as far as im concerned opera browsers are old and outdated thats probly why they dont work rite

opra is a bit over the top with its w3 complicance, make sure you have the doctype at the top (one wich supports it). also try googling the problem as others who may have faced it may have come up with soltions. if that fails you can also be in the confute that only a small handful of people realy use opra anyway "/
