Bug 12233 – word-spacing of negative length adds righthand padding, ignored(?)

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[D. Brodale]

Compare referenced URL to Firefox, Opera, and IE/win.

Scroll to page base, and inspect pagination block (i.e.,
"Page 1 (of 12)...") represented by <div class="pages">.

Note that the individual page listing is offset from the
righthand edge of that block, despite being floated to
the right. The contents of that floated child <p> is a
simple collection of <a>s and <b>s and separating
character entities.

Relevant CSS applied to contain <div class="pages">
and its contents:

#C p { margin: 10px 10px 0; font-size: 11px; line-height: 1.35; }
#C p a:link, #C p a:visited { color: #981C25; font-weight: bold; }

#C .pages { clear: both; margin: 20px 10px 0; border: 1px solid #94C5EA; border-width: 1px 0; }
#C .pages p { margin: 0; padding: 6px 0; line-height: 1; }
#C .pages p.f { float: left; margin-right: 5px; }
#C .pages p.l { float: right; word-spacing: -.25em; }/*!sf(2)==w-s(-.25em)*/
#C .pages p a:link, #C .pages p a:visited { font-weight: normal; }
#C .pages br { clear: both; }

Application of word-spacing as given triggers this layout misfire.
I'm baffled as to why, and it's not immediately apparent whether
word-spacing is even affected regardless of the additional righthand
padding produced.

Seen with both Safari 2.0.4 (419.3) and WebKit r18794.

First Cut @ Standalone Issue Demonstration


Adding attachment that should visibly demonstrate how Safari compares
to other browsers (I checked against Opera 9 and Firefox 2 before upload).

What seemed the most relevant css is given within the attached document.
Each example includes variants in <p> content in the following order:

 * anchor/text sequence, one blank line between within markup
 * anchor/text sequence, no blank line between within markup
 * anchor-only sequence, one blank line between within markup
 * anchor-only sequence, no blank line between within markup
 * text-only sequence, one blank line between within markup
 * text-only sequence, no blank line between within markup

I see marked differences between Safari and other browsers in
terms of handling. I also see marked differences between Safari 2.0.4
and WebKit Nightly (r18794).

Not much of a reduction yet, but this ought to make the issue more
accessible to anyone who wants to help provide (better) test cases.

Confirmed with locally-built debug build of WebKit r18820 with Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8N1037).

I'd say that was a pretty clear reduction!

...after you know that the blue bars in each group should be the same length.

This is rendering correctly now. Closing.
