"List question" is meta jargon on stackoverflow that longtime users will understand. It falls under these "open ended" questions, hence why OP's question was closed as "primarily opinion-based" - IIRC it used to have its own close reason but got rolled into that when others were needed.
Here's a meta question specifically about list questions that says basically the same thing: https://meta.stackexchange.com/questions/139618/are-list-que...
I'll be honest, I mainly knew what the answer to your question would be, but I tried to put myself in the shoes of a newer user trying to understand what questions a person should ask on SO and was curious of maybe things were different.
And the answer appears to still be some form "you won't know until it's closed".
> and asked for other concrete examples.
It's explicitly asking for an open-ended list.
If your goal is to come with any reason to label a question a "list question", then I don't think it would be too hard to find a way to label any potential question as a "list question" and have it closed.
A different interpretation would be that the question is about whether there are maintainability issues with a certain implementation of CSS. Which the question being potentially answered with a "Yes/No" where an obviously better answer might provide an example or two of issues that could arise.
There are questions that are somewhere in between, something like "which approach is better here?". Those tend not to go well on SO even though they theoretically could be on-topic. This is a case where the community is sometimes overzealous, but it's extremely hard to consistently apply these rules to complex edge cases. And many questions of this kind do not fit to the rules and are closed correctly. These questions usually require quite a bit of familiarity with SO to formulate them in a way that works on the site.
How many examples would they have to post in order for you to be satisfied?
