 CSS Profiles</h3>
 
 	Not all implementations will implement all functionality defined in CSS.
-	For example, an implementation may choose to implement only the functionality required by a CSS Profile.
-	Profiles define a subset of CSS considered fundamental for a specific class of CSS implementations.
-	The W3C CSS Working Group defines the following CSS profiles:
 
-	<ul>
-		<li><a href="https://www.w3.org/TR/css-mobile/">CSS Mobile Profile 2.0</a>
-		<li><a href="https://www.w3.org/TR/css-print/">CSS Print Profile 1.0</a>
-		<li><a href="https://www.w3.org/TR/css-tv">CSS TV Profile 1.0</a>
-	</ul>
+	In the past, the Working Group published a few Profiles,
+	which were meant to define the minimal subset of CSS
+	that various classes of User Agents were expected to support.
+
+	This effort has been discontinued,
+	as the Working Group was not finding it effective or useful,
+	and the profiles previously defined are now unmaintained.
 
 	Note: Partial implementations of CSS, even if that subset is an official profile,
 	must follow the forward-compatible parsing rules for <a href="#partial">partial implementations</a>.
