-	[[CSS-MULTICOL-1#column-gaps-and-rules]] allows for rules to be drawn
-	between columns in a <a>multicol container</a>. This specification expands
-	upon the 'column-rule-width', 'column-rule-style', and 'column-rule-color'
-	properties, adding equivalents in the row direction, expanding their
-	application to other container layouts, and giving advanced control over
-	where and how gap decorations are painted.
+	[[CSS-MULTICOL-1#column-gaps-and-rules]] defined properties that allow
+	authors to control the spacing between columns in a [=multicol container=],
+	and to paint visible separators such as lines in those spaces.
+	We refer to these visible separators as [=gap decorations=].
 
+	This specification expands upon the previously defined properties.
+	It adds equivalent properties for the row direction,
+	applies the full set of properties to other container types,
+	and gives additional control over where and how gap decorations are painted.
