 Inline formatting contexts</a></h3>
 
-<p>Rather than define &ldquo;zero-height line boxes&rdquo; that must
-be ignored next to a margin, define precisely when an empty element
-generates no line boxes at all and define separately what the static
-position of positioned descendants is.

-no text, no preserved white space, no inline elements with non-zero
-margins, padding, or borders, and no other in-flow content (such as

-<ins>The <a href="visudet.html#static-position">static
-position</a> of any child elements is the top of the box in the

-width, zero height inline replaced element would have if placed in the
-element. (This, for example, respects the <span

+<p>Empty line boxes aren't generated at all, rather than just ignored
+for margin collapsing. But their virtual position must still be
+calculated if they contain empty inlines with absolutely positioned or
+floating descendants:

+<blockquote>
+<p><ins>Line boxes are created as needed to hold inline-level content
+within an inline formatting context.</ins> Line boxes that contain no
+text, no <a href="text.html#white-space-prop">preserved white
+space,</a> no inline elements with non-zero margins, padding, or
+borders, and no other <a href="#positioning-scheme">in-flow</a>
+content (such as images, inline blocks or inline tables), and do not
+end with a <del>line feed</del> <ins>preserved newline</ins> must be
+treated as zero-height line boxes <ins>for the purposes of determining
+the positions of any elements inside of them, and treated as not
+existing for any other purpose.</ins> <del>For the purposes of
+margin collapsing, this line box must be ignored.</del>
