List marker boxes lost to right of a floated image
Closed, DeclinedPublic


Author: mfc

The bullets on a bulleted list to the right of a left-float image
are hidden by the image (using IE) or overlap the image (using
Firefox). Here is a testcase which demonstrates the problem if
enterter into the Wikipedia sandbox:

Try a float left image with bullets to right.
[[Image:Sandbox25703 5762.jpg|thumb|left|A large, loosely contained
sandpit for kids]]

Here is some text

*And a bullet
*Another bullet
*Third bullet

And more text.

Version: unspecified
Severity: minor

either way, this is basically a browser and/or standards bug and our ability to
fix it may be limited.

Can anyone else confirm that this bug occurs in Firefox? Using, I get
expected behavior, namely that all bullets are fully visible and don't overlap
with the image.

No. In Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/20060731
Ubuntu/dapper-security Firefox/ I see it all correctly. No bullets missing.

My Firefox was slightly downlevel; I just updated to the latest, which is:

text of each bullet lines up with the (unbulleted) text above and below.
There's no hint of a list, which is extremely misleading.

Firefox just started automatic update when I
looked at that URL a few minutes ago (2006.09.19 17:35

I've attached an cropped screenshot showing the relevant

A picture is worth a thousand words. Confirmed for Cologne Blue, Nostalgia,
Classic, and partly for Simple, in latest Firefox. Monobook and Chick are
unaffected, because Firefox draws the bullets on top of the border, and the
div.tleft border in Monobook/Chick is thick and the same color as the
background, basically a pseudo-margin. I've greatly expanded the test case:
take a look at the URL and you'll be able to see clearly how what happens here.

So why does this occur? I'm not clear enough on the CSS to figure it out
exactly, but seemingly the list marker box is supposed to go inside the border;
IE puts it beneath, Opera and Firefox above. Why it's not to the right of the
margin, I have no idea, but it seems likely to be part of the standard
(something about only line boxes being compressed next to floats, I think I recall).

Anyway, on a case-by-case basis the behavior can be manually tweaked by adding
left margin to the list items. There's no way for MediaWiki to know whether a
given list item will be rendered to the right of a float or not, so it can't be
done software-side; as such, either the styles need to be modified to account
for this corner case unobtrusively, or it has to be written off as a standards
bug. Anyone want to play around with their CSS to see if they can get something
that looks good without changing the look too much?

A partial fix is to add a wider border on the right of the image itself .. but
this then pushes 'normal' lines of text out to the right of the bullets.



Whatever has been done to get the test case working was not working for me in with the following:
Mozilla Firefox version "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/20080201 Firefox/"
Microsoft Windows Internet Explorer 7 (IE7) version "7.0.5730.11"

This is normal HTML/CSS behavior. The fix is to add (for vector):

#content ul, ol {

list-style-position: inside;


But I'm not sure what kind of effect that might have on our existing content (seems to shift the content more than before), nor do I know how well it is supported in browsers. Perhaps it's time to find out however.

Works fine in recent browsers (FF2, Webkit), and is probably not big enough of an issue to justify all list indentations.
