[07:34:52] Argh! Why am I not finding any documentation of what MF actually /does/ to id=mf-… prefixed elements? [10:57:34] It /looks/ like it turns off borders and sets margins to 0. [10:58:01] Does it also set width and max-width? [11:03:59] Hmm, oh, perhaps not. MF doesn't load Common.css, so what I'm seeing is probably rather the /absence/ of those styles than added tweaks by MF? [11:18:00] No, that doesn't make sense either. [11:23:25] Ok, comparing the code it looks like at the very least it's stripping inline style="" attributes on headings. [11:24:32] And all div elements without a mf- prefdixed @id? [11:25:54] Hmm. Unless the div comes from a transclusion, like a template? [11:26:46] Or maybe it's unless it is /contained/ in a mf- prefixed div? [11:33:19] (aside: if you write code—both code-code and web "code"—and don't document your stuff /religiously/ I'm going to assume it's because you hate me and want me to suffer!) [11:38:10] But, ok, let's assume what I'm seeing is the result of stripping non mf- container divs, plus stripping inline styles on non mf-prefixed elements or elements not contained inside a mf- prefixed element. [11:39:11] The relevant styles affecting stuff on the .m. proxy would then be coming from Minerva. [11:41:53] And since my Template:Main_Page/styles.css rules are /not/ getting stripped by MF, my sandbox through .m. is showing styling that used to be stripped. [11:42:41] Yeah, ok, I think that hangs together. At least as a plausible starting hypothesis. [11:44:41] Implication: I need to reproduce Minerva's default styling in my media query to override the desktop styles. [11:45:24] (well, or flip the default for mobile-first, I suppose, but the main point remains the same) [11:47:53] Now to go looking for the relevant bits of Minerva… [11:51:08] But is there a nice prominent link on mw:Skin:Minerva to "minerva.css" to check? Of course not. That would have been way too easy and obvious. [13:53:04] Aha! /me holds a literal lightbulb up over the head… [13:56:48] I'm generating bits of the main page with templates, that each use templatestyles, that all target desktop; only my mainpage styles are mobile-first/responsive. [13:56:57] "D'oh!"
