-	- The start of the line-clamp container.
-	- A point between two [=in-flow=] sibling boxes in the line-clamp

-	- A point between two [=line boxes=] in an in-flow [=inline formatting

-	- The end of the line-clamp container.

-	Note: The [=clamp point=] can never be before a parent box's first child, or
-	after a parent box's last child, unless that parent box is the line-clamp
-	container. Similarly, the clamp point can never be before the first line or
-	after the first line of an [=inline formatting context=]. It can also never
-	be in [=out-of-flow=] content, or inside an [=independent formatting
-	context=].
+	- A point immediately after a [=line box=] in the line-clamp container's [=block formatting

 	If the [=line-clamp container=]'s [=block formatting context root=] has a [=computed value=] of
 	'max-lines' other than ''max-lines/none'', then that property will determine the [=clamp point=].
 	Otherwise, the clamp point will be set to the last possible clamp point such that, for it and
 	all previous possible clamp points, the line-clamp container's [=automatic block size=] (as
 	determined below) is not greater than the [=block size=] the box would have if its automatic
