 # Test Suite for CSS 2.1, 8.3.1 Collapsing margins - See Bug 477462

 # Based on CSS 2.1: http://www.w3.org/TR/2011/REC-CSS2-20110607/

 # and its Errata, Last revised: $Date: 2013-09-09 17:40:16 $

 # The structure of this manifest is intended to resemble the structure of

 # the prose that defines collapsing margins. As a result, there are several

 # sections where inline-block-, block-, and other- series are combined.

 # E.g. the first section is about horizontal margins and includes both

 # inline- and block series.

 # "Horizontal margins never collapse."

 # Horizontal margins of inline boxes do not collapse.

 # The norefs for these tests depict margins that incorrectly collapsed.

 # * table-caption boxes, per CSS 2.1 §9.4.1 (Block formatting contexts):

 # "[...] block containers (such as [...] table-captions) [...]

 #  establish new block formatting contexts for their contents."

 # The margins of a table-caption do not collapse with the margins

 # of the table wrapper box. They can collapse with the margins of other

 # table-captions, though, if they share the same caption-side.
