Using CSS such as img:before {content: "text"; } was working in the Firefox 0.8
release. Using a recent Firefox 0.9 branch build [Mozilla/5.0 (Windows; U;
Windows NT 5.0; en-US; rv:1.7) Gecko/20040604 Firefox/0.8.0+] this CSS no longer
works.
I have been unable to find any mention of this in Bugzilla, but saw the
following post in the forums:
http://forums.mozillazine.org/viewtopic.php?t=69087
Reproducible: Always
Steps to Reproduce:
1. Add the following CSS to a page: img:before { content: "text"; }
Actual Results:
The text does not appear.
Expected Results:
The text should appear before all images.

'::before' and/or '::after' don't apply to replaced elements.

Oh yes? Then how did this example creep into the CSS2 specification:
-----
12.2 The 'content' property
(...)
The next rule inserts the text of the HTML "alt" attribute before the image. If
the image is not displayed, the reader will still see the "alt" text.
IMG:before { content: attr(alt) }
-----
In case this was changed in CSS2.1, CSS3 or with an Errata then at least say so.|

You should not look in CSS 2.0. It is bogus for quite some parts, especially that example is really bad. They never really thought about it, I guess.

(In reply to comment #3) Ok, after looking at 169334 I see the Mozilla crew has decided that the current implementation is the right one. I don't no whether it matters but I think duplicate of bug 169334 would be the better resolution of this bug: to point people searching bugzilla for an explanation why that example doesn't work any more in the right direction.
