Thank you for replying.
I have a file called base.html.twig, which seems to contain all the general HTML used across the site.
I also have a file called home.html.twig, which contains the HTML that is only on the top page.
If I understand you correctly, you’re saying I should make a copy of base.html.twig, rename it base2.html.twig (or whateve name) and edit base2 to give my DIV the right styling, then make home.html.twig refer to base2.
(I’m not totally sure how to link home.html.twig to a different base file, but I’ll see if I can figure it out.)
This seems like a workable solution, but I’m concerned about the long term upkeep. If I do this, doesn’t that mean if I make any edits to base.html.twig, I’ll have to make sure I also make the same edit in base2.html.twig?
Having two copies of the same file where everything is the same except for just one DIV seems to be very inefficient and prone to human error down the road where I edit one and forget the other.
Is there no way to create something more conditional, where I can say, “This DIV is always like X, except on the home page, where it’s like Y”? Or somehow separate that DIV out of the flow so that I don’t have to maintain two copies of the same code?
