relative: out of the document flow, but it's position is relative to its original position in the document flow.
absolute: out of the document flow, but it's position is relative to non-static element out of the document flow. So its parent can be relative, absolute and fixed.
fixed: out of the document flow, but's it's relative to viewport.
static: just in the document flow
