+# 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.
