rootpage_MainPage could be used to distinguish the main page in CSS. There is also a main page stylesheet.

The mobile main page stylesheet is defined by MobileFrontend. It's a magic RL module that loads the MediaWiki:MobileMainPage.css page as a CSS asset.

Also this is AMC only.. not main page. That might impact what we do here. We might prefer a server side HTML solution.

There's some discussion about whether it would be better to hide the tabs in CSS or never send the HTML in the first place. The benefit of the former is the change is made only to presentation. The benefit of the latter is no possible confusion for screen readers and improved bandwidth.

@Jdlrobson Can you take a look at the QA steps 3 and 4. When I toggle AMC off I see the Discussion button. When I toggle it on, I don't see it. It seems like a Fail, but I wanted to make sure the QA steps were correct.

Good catch. I think this is okay (the discussion button is available on all pages when outside of AMC mode).

We're ready to resolve here. The questions remains that we do have a small inconsistency where there is a talk page button for non-AMC users and not one for AMC users. @alexhollender - are we okay with this or do we want to follow up with another task for adding the button back to the bottom of the page?

My apologies for not thinking about this earlier. I do think it's necessary to have some way to get to Talk page of the Main page, although I'm not sure where that falls in the priority of things. I assume it's relatively low, although a counter point I can think of is that since the Main page is so visible, editors might notice that in AMC mode there is no discussion button, and potentially take a less favorable opinion of the feature. One way or another I'm fine with moving this task along, given the current state. Thoughts @Jdlrobson @ovasileva?

@Jdlrobson good catch...looks like we missed that as a QA step. Adding it now.

@alexhollender - although, is this such a bad thing given it's the talk page? The talk page also has the actions bar as well, so in terms of consistency it might make more sense for it to mirror other talk pages.

@ovasileva interesting point. I guess it could go either way. To have the tabs on the talk page but not the page itself is a bit inconsistent — it becomes kind of this hybrid of AMC and non-AMC, which might be harder to test and keep track of (?). I'm not opposed to leaving it though and revisiting this later if we feel we need to.
