Continuing on from this message, the goal was to make a nice heading solely for aesthetic purposes which was done on the main page.
It was a lovely amount of confusion all round, because that My Hero Academia one turns out was also using it for multiple purposes - I was just after emulating the nice template design so wondered why there was a copious amount of CSS.
Yet figured out what it may have been used for, but may very well complicate into a third interpretation of what is thought was in mind. With the CSS I thought maybe the headings on a page could match the infobox design. The only way to describe it is this page see how the
La historia tiene lugar en una ciudad ideal conocida como "N º 6".
Looks the way it does there? If CSS could have the navigation headings the same blue as the infobox that is what I thought you thought I had in mind. Whilst it is nothing urgent, if that is possible to be able to do, it's certainly worth looking into since customised headings on a page simply looks nice but may need to be a different wiki to the Given one.
Now, as for this My Hero Academia doomsday heading, is there an example page where the effects can be seen? Because what that does is probably different to even these ideas.
