Hi, @stephan-romhart, @terry-r and All,
Oooooh, Stephan, I see ! Actually, it’s the comments, themselves, that are the objects to look for ;-))
Then, just for your information, here is a shorter version of the two regexes, within the css_comment.xml file contents :
<?xml version="1.0" encoding="UTF-8" ?>
<NotepadPlus>
	<functionList>
		<!-- ================================================ [ CSS comments ] -->
		<parser id="css_comment" displayName="CSS" commentExpr="">
			<function mainExpr="/\*{2,3}(?i)[A-Z0-9\xc4\xd6\xdc\xdf -]+\*/" displayMode="$functionName">
				<functionName>
					<nameExpr expr="(?i)[A-Z0-9\xc4\xd6\xdc\xdf -]+" />
				</functionName>
			</function>
		</parser>
	</functionList>
</NotepadPlus>
With the added line, in the configuration file overrideMap.xml :
			<association id= "css_comment.xml" langID= "20"/>
As the default CSS association is :
	<!--	<association id= "css.xml"	langID= "20"/>  -->
Note that the added line, in the overrideMap.xml file, is not mandatory. But, in that case, you must rename the css_comment.xml file as css.xml !
