User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8a4) Gecko/20040921 Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8a4) Gecko/20040921 Visiting several projects in mozdev.org, the middle column renders below the lowest part of the left column (though remaining in the middle column) when you click on the middle column's "resources" navigation on top. (This navigation usually has "Home Mailing List Installation Source Code Members Screenshots" links). So it is like the left column becomes its own row. It will bounce back up if you resize or refresh the browser. Same error is in the 20040921 Firfox trunk nightly. However, these pages will render propperly in Linux/Mozilla 1.7.1, & had before in my Mozilla 1.7beta on Win98se. Looking at the HTML code, the mozdev pages look like a mish-mash of CSS columns & tables. The said "project-navigation" is contained in a table, which in turn is in <div id="main-content">. I checked several CSS 3-column examples at http://css-discuss.incutio.com/?page=ThreeColumnLayouts & I am unable to repeat the same mozdev rendering error. Reproducible: Always Steps to Reproduce: 1. visit http://vssdoclinks.mozdev.org/ 2. click on a link in "resources" navigation on top 3. middle column will drop 4. refresh/resize, midlle will return to the top Expected Results: render the middle column flush to the top
Possibly related to Bug 260442?
I´m duping this to bug 260963 as I´ve commented there a lot of numbers. broken : Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8a4) Gecko/20040916 working: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8a4) Gecko/20040911 broken Build ID 2004091605 major, as it is a highly visible regression. *** This bug has been marked as a duplicate of 260963 ***
Created attachment 160062 [details] testcase minimal testcase made from http://www.mozdev.org/logs/top50.html 3 divs with visible borders to show what is going on.
I´m reopening this bug, as Bug 260963 is wfm now. Simple testcase attached: https://bugzilla.mozilla.org/attachment.cgi?id=160062&action=view Maybe it is related to Bug 260442, but I can´t test, as I can´t test on linux and don´t have a slashdot account.
Confirming based on testcase Bug 260963 comment 7 was showing a regression timeframe between BuildID 2004091105 working and BuildID 2004091306 broken http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=SeaMonkeyAll&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2004-09-11+00%3A00&maxdate=2004-09-13+08%3A00&cvsroot=%2Fcvsroot maybe Bug 257216? Fix sundry block issues for columns. In particular, remove overflowing floats from the space manager before we compute the space manager's XMost and YMost to include in the block size. r+sr=dbaron"
Created attachment 160089 [details] [diff] [review] fix This exposed some confusion about whether nsLineBox::mBreakType means break *before* the line or *after* the line. Turns out it's *before* the line for blocks and *after* the line for inlines. I added new methods in nsLineBox.h to make this explicit and changed the relevant code in nsBlockFrame to explicitly look for before or after breaking. This fixed the bug here.

thanks roc, for the fast action requesting blocking 1.8a4 would be nice if mozdev.org won´t show this bug with 1.8a4
thanks for looking into this (I'm the original bug-submitter). "would be nice if mozdev.org won´t show this bug with 1.8a4" IMHO, I'm glad it was caught early, as this bug may have grown worse in time. But it is funny I first noticed it on a moz site :)
I see this on Linux also. www.xulplanet.com is badly affected, too.
I assume fixing this bug would also fix some others from the list of Bug 261196, maybe Bug 261153 if you click a link, move a link Bug 260442 Form elements jump when form buttons pressed ( posting at slashdot!)
(In reply to comment #10) > I assume fixing this bug would also fix some others from the list of Bug 261196, > ...Bug 261153... Bug 260442 Yes, they all seem related, since I get the same behavor at mozdev.org
