CSS Issues w/ Comment DIV and Width

I don't know whether these are one or two issues. From the site developer point of view, they are one, since they affect the ability to use CSS to theme comments.

1) The Post New Comment block isn't really a block

1a) the h2 title "Post new comment" is not in the same DIV as the rest of the form (#comment_form). This means that, for instance, you can't put a single box around the entire new comment box.

1b) the h2 title "post new comment" has no unique class or ID, so it can't be themed. If it were wrapped inside #comment_form, this would be OK.

2) "Post New Comment" width issues

If you try to use CSS to set the width of #comment_form, it works EXCEPT for the "Subject" entry box, which retains its original width. If you set the width of #comment_form to, say, 1/2 the normal page width, the "Subject" field pokes out beyond the right border of the #comment_form.

My handy Firefox Web Developer toolbar says that while the comment body is 60 columns but class "resizable," the 60 column subject field has no such "resizable" class.

I think I see where these fields are set in lines 1315 - 1318 of comment.module ... is it that textfields are not resizable, but textareas are?

Unfortunately I only know enough to ask these questions -- answering them is beyond me at this point!
