The sidebar.xul file contains a rule that is applied to column headers when the sort is active that should cause a grey background to be mapped down an entire column. The rule is treecol[sortActive="true"] { background-color: #404040; } This rule doesn't work. The column does not honor the background color.

I think this is fixed now (for standard mode). There was another bug on this, bug 4510.

Problem remains. The light green colour in sidebar.css happens to co-incide with current behaviour. However, changing this file makes no difference to the rendering.

This might be an issue of standard vs. nav quirks mode. Try it in both modes and see.

Aaah! The wonderful compatibility mode. How do you engage this under Apprunner? Or can I test this in Viewer somehow? I'm using M7 for my tests.

With apprunner, you're automatically in standard mode (the mode you want). If it works in apprunner, then I'd consider this bug fixed.

No, you're not automatically in standard mode in apprunner. In fact you're more likely stuck in quirk mode (unless someone did something to the prefs or pres context there that I don't know about). The plan is (and I have almost all of this working on my machine) that you're locked into standard mode for XML documents (XUL included) (therefore no quirks in chrome). For HTML documents, the quirk mode will automatically be selected unless the document has a DTD of 4.0 strict or later.

Right now, I have a hack in apprunner to automatically place the user into standard mode. The problem that forced this was basically a need for chrome to be in standard mode. If there's going to be something better than the single global pref (which does not make sense to me), then I can remove the hack. Let me know when this comes online, and I'll nuke the hack.

Ok, I will. That also explains why we were seeing other nav quirks failing to turn on in apprunner...

Still not working on this morning's build (28/06/98), under 95. Background colour shows up as light grey in this build -- it was light green for M7. It may be the [sortActive="true"] modified that it's not picking up. If I remove it from sidebar.css the background colour will change.

Moving to M9.

Backgrounds on columns an column groups were implemented in Standard mode some time ago. If this is still a bug, please reopen it, after providing an updated way to duplicate the problem; the current instructions involving sidebar.xul are outdated.

Will verify fixed based on Karnaze's comments. No test case available.
