Status: VERIFIED DUPLICATE of bug 6865

Description

This bug was forwarded to me by one of MozillaZine's readers.

The problem seems to be extra linespacing between the last two lines of a piece
of text which can be alleviated by adding an extra space before the close font
tag. A link to a simple example is below. This problem is visible in the 3-24-99
nightly build on Windows 98. Visit the link below, and try resizing the window
so the lines of text wrap a couple of times. You'll see the line spacing error
on the top sample. The bottom sample shows the problem resolved.

Here's text from a newsgroup conversation about this specific bug:

"http://www.netmeet.net/bug_not_fixed.htm

The workaround for this bug is to put a space before the end of each font tag.
This is a real pain in the ass and I'm not sure why it happens. I'm copying the
Internet Explorer team so they can fix this issue on future versions of their
browser. The problem shows up mostly in "size 1" font tags, but I've seen it at
other sizes as well."

I have verified that this problem is visible in NN4.5, and IE5 as well. This bug
was forwarded to me by Robert Gelb ([e-mail]).

Can this be reproduced using CSS? I will investigate.

Believe it or not, it is the fact that *adding* the space *removes* the
spacing which is the bug, not that removing the space adds the spacing.

That is, according to CSS2, the extra spacing is the correct behaviour.

The dodgy behaviour you see is due to the block level parent's line-height
being ignored. This is covered by bug 6865.
