ol li:first-letter { font-weight: bold; } in an external stylesheet does not
work as expected with ordered lists; I've tried this to emphasize the numbers 1.
2. etc. at the start of each <ol><li>entry</li>...</ol>. With IE 6, they appear
in bold type, as expected.


Reproducible: Always

Steps to Reproduce:
1. Create a html-page with a simple ordered-List and the above mentioned styledef
2. load this page into the browser

Actual Results:  
The numbers in front of the list items are NOT boldfaced!

Expected Results:  
The numbers should be formatted according the style-spec

I know no other way to format a numbered list, so that the numbers in front of
the list items are boldfaced, for example. So I have to use CSS, which not works
as expected...

This looks like correct behavior.  The list-item marker is not the first
letter.  Whatever the first letter of the content of the <li> tag is
constitutes the first letter, and is being bolded by Mozilla.

Opera 7 also renders as Mozilla.

Ian, what does (or should) css3-lists/css3-content say about this?  I think per
CSS2 our behavior is actually incorrect.

Comment 3

[Bill Mason]

Just to document then, if this is a bug, IE6 bolds both the list-item marker and
the first letter of the actual <li> content.

[Hixie (not reading bugmail)]

CSS3 says that the :first-letter will match the first letter of the list item if 
the list item is 'list-style-position:inside', and not if the list item is 
'list-style-position:outside'. Basically, 'inside' makes '::marker' work 
something like an inline '::before', but 'outside' makes it work like an 
out-of-flow box that just happens to take part in the inline box model.

new testcase reflecting the two options in Hixie's comment.

Comment 6

[Bill Mason]

Confirming new since one of the exhibited testcase behaviors must be a bug then,
since they render the same where :first-letter is concerned.

Just not sure I understand yet which one is the bugged behavior, or I would
resummarize this bug.  :)

Hmm, since UAs seem to agree on this, maybe I should change the spec.

Comment 8

[mark hosang]

a similar bug with bolded font weight not rendering correctly exists in firebird
0.7 on winxp as well.  Following code does not render text in bold.  Renders in
IE 6.0 correctly.  The following code was snipped from jan 2nd entry of
http://www.xanga.com/home.aspx?user=squarebox 


<font size="6" style="font-weight:
bold;">&#12354;&#12369;&#12414;&#12375;&#12390;&#12288;&#12362;&#12417;&#12391;&#12392;&#12358;&#65281;<br>
<br>
</font>

Seems like a good idea.  If/when CSS3 introduces ::marker it gives greater
freedom to style ::marker/::first-letter independently if the current UA
behaviour is kept as is.

Mats, I'd send mail to www-style about spec changes...

Comment 12

[Hixie (not reading bugmail)]

CSS2.1 defines this case, by the way. (Or mentions it. I forget if it
technically actually _defines_ it per se.)

Comment 13

[Mats Palmgren (inactive)]

It turns out CSS 2.1 is already clear on the matter:

http://www.w3.org/TR/CSS21/selector.html#first-letter
  If an element is a list item ('display: list-item'), the ':first-letter'
  applies to the first letter in the principal box after the marker.
  UAs may ignore ':first-letter' on list items with
  'list-style-position: inside'.

Note the "after the marker", which makes this bug invalid.

To my surprise CSS3 is less clear, I checked both the Line and List modules:
http://www.w3.org/TR/2002/WD-css3-linebox-20020515/
http://www.w3.org/TR/2002/WD-css3-lists-20021107/
but could not find this case mentioned.

-> INVALID

Both of those drafts are older than the CSS2.1 spec.
