Just came across with this post:

The guy who wrote it wonders if there's a contradiction in CSS 2.1.

1. In "11.1.1 Overflow: the 'overflow' property" there's an example
stating "the <blockquote> to be clipped by the containing block." [1]
2. In this case, the containing block is "formed by the content edge
of the nearest block-level, table cell or inline-block ancestor box."
3. However, the overflow "specifies whether a box is clipped to its
padding edge," not the content edge. [3]

That's what the guy basically says. I think that's not a contradiction
but I do think the example needs to be more accurate. Saying that the
<blockquote> is clipped by the "containing block" would only work for
this particular case, where the content edge is the same as the
padding edge.
