1 — clip: rect(top, right, bottom, left)

Only the region inside the rect is painted; top/bottom are offsets from the top edge, right/left are offsets from the left edge (not a width/height pair).

2 — auto on some edges leaves that side unclipped

clip: rect(auto, 130px, auto, 30px) - top and bottom keep the box's own edges; only left/right are cropped.

3 — position: static ignores clip entirely

Per CSS 2.1 §11.1.2, legacy clip only applies to absolutely/fixed positioned elements - the same rect() value here has no effect at all.
