Hello.

Should /margin/ properties take effect on absolutely-positioned blocks?
I thought not, but the referred sample HTML [1] seems to prove me wrong
both on IE 6.0 and Firefox 0.8. I thought the /margin/ property should
have no effect, since the location of the positioned block is being
controlled by the /top/, /left/, etc. properties. The CSS2 Specification
states:

"Positioned elements generate positioned boxes, laid out according to
four properties: [top, right, bottom, left]"

There is no mention of /margin/. So, if I intend to have a block at (0,
0), I should only have to set /top/ and /left/ to 0 and not be concerned
about setting /margin-top/ and /margin-left/ to 0 as well.

Does anybody see something in the text of the Specification which I may
have missed?

Not in that place. Read whole spec sometime, it has lots you have missed.

This, for example.

Especially the blockquote in the middle of that section. I wonder where
they quoted it...
