title: How to disable margin-collapsing?
body: <p>Is there a way to disable margin-collapsing altogether?  The only solutions I've found (by the name of "uncollapsing") entail using a 1px border or 1px padding.  I find this unacceptable: the extraneous pixel complicates calculations for no good reason.  Is there a more reasonable way to disable this margin-collapsing?</p>
