(Current Camino-trunk build, Mac OS X 10.3) scrollWidth is returning wrong values for <pre>-elements, the returned value is the same as the offsetWidth. Safari gets this right. Reproducible: Always Steps to Reproduce: 1. Load testcase 2. Click the "Show sizes"-button 3. Compare the values to other browsers This is similar to bug 209807 so cc'ing bz.
Created attachment 231333 [details] Testcase The script and button is stolen from the testcases in bug 209807.
Er... So what _should_ scrollWidth return? Note that the <pre> is not scrollable, so its scrollWidth _is_ the same as its offsetWidth, based on all the documentation I've seen. This has nothing to do with <pre> elements, of course. The relevant code is the same for all HTML elements: <http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/content/html/content/src/nsGenericHTMLElement.cpp&rev=1.663&mark=1158-1160#1147>. I should note that in IE/Windows I see scrollWidth == offsetWidth on this testcase as well. Of course the offsetWidth is different from that for Gecko, but that's due to an IE bug in CSS rendering. Put borders on your <pre> to see the difference there. It sounds like Safari is returning the same offsetWidth as Gecko but the same scrollWidth as IE on this testcase; that's incorrect behavior...
