Yes: Use valid CSS. ;-)

The commas are invalid. What you should have said was:

   h1 { margin: 0 0 1em 0; }

You will find that kind of details in the spec:

   http://www.w3.org/TR/REC-CSS2/

Also, a validator would have told you that your CSS was invalid:

   http://jigsaw.w3.org/css-validator/

The problem is that Windows IE 5.0 is ignoring a large section of the
CSS spec, mainly the forward compatible parsing rules. Mac IE 4.5 is
correctly ignoring the property/value pair, since it uses incorrect
grammar. 

Now that you have been burned by the lack of compliance in popular
browsers, do something about it:

Or, e-mail your complaint directly to Microsoft: wasp@microsoft.com
