Hey, Brojogon here! When it comes to non-conforming pages I see, I become the meanie of the Wiki, but this page exists on LittenGMD's userspace, not the mainspace, so I have nothing to get my Karen self mad at. Instead, let's twist an element of this page into something positive. I'm talking about the inclusion of multiple flags into the gender infobox. Of course I won't approve such a thing in the mainspace if nobody does, but I believe we should tolerate it in the future, and it's okay if you disagree. First I'll show you how including multiple images can be done in the infobox, then I'll explain its main benefit.
First, here's what the inclusion of multiple flags in the gender infobox looks like. As soon as I saw this page, I knew I had to talk about its interesting visual effect.
This is how the effect shown was coded: (simplified)
{{Gender|image1=<gallery>
Male.png|Male
Female.png|Female
Mix.gif|Mix (⚠)
</gallery>}}
Then, I want you to check out the main benefit of this effect. I included Content Warning.png and the original sonnegender flag in the same infobox of a dummy blog post, because I'm not allowed to execute this example on any mainspace pages yet.
In summary, the inclusion of multiple flags into the gender infobox is a compact alternative of the Gallery heading, and it has debatable potential to be used as a warning for disturbing flags. However, captions don't work on this effect, so it raises one question: how can we credit the respective designer of each flags?
