<!-- The SPANs here will be wrapped inside anonymous blocks. #div-parent will
|
|
thus start with an anonymous block (for the first SPAN). When looking for a
|
|
first formatted line, it will have to be inside this anonymous block (or it
|
|
doesn't exist at all).
|
|
|
|
To quote the spec:
|
|
|
|
The first formatted line of a block container [...] that contains
|
|
block-level content [...] is the first formatted line of its first in-flow
|
|
block-level child. If no such line exists, it has no first formatted
|
|
line. -->
