IE rendering differences between win versions

[Tripnologist]

Anyone noticed this?

IE will often ignore bottom margin, we all know this. FF, Opera, etc, they handle it how they should.

However, I've just come across an actual browser variation depending on OS.
on Win7 with IE8, bottom margin is applied but with IE8 on XP or Vista, it's not applied.

As far as I knew, IE always rendered the page the same regardless of what version of windows you had. It was only the version of IE which mattered. Apparently not anymore.

No, nothing at all.

I usually always use bottom padding where I can, or alternatively use top margin on the lower element as I'm not sure what causes IE to ignore bottom margin as it doesn't always.

Just thought I would ask to see if this was a commonly known thing (which I doubted), and to warn anyone else who might run into it.

It's just margin collapsing.

In my case, it was floated elements with bottom margin, inside of a cleared container, so the container should have included the margin in its dimensions.
