My CSS Theme

<baris>

Maybe you can take a look at nodebb-theme-lavender, it is a child theme based on vanilla in nodebb 2.x and persona on nodebb 3.x
nodebb 2.x https://github.com/NodeBB/nodebb-theme-lavender/tree/v6
nodebb 3.x https://github.com/NodeBB/nodebb-theme-lavender/tree/master

In theme.json the baseTheme is set to the parent theme "baseTheme": "nodebb-theme-persona" and in the main style file the scss/less of the parent theme is imported. https://github.com/NodeBB/nodebb-theme-lavender/blob/master/theme.scss

If you share the error messages you get we can help more.

I'm going to try again. If I have any problem I will discuss it with you.

One question, I don't know the roadmap well, but if I make the theme for v2.x later, will it be very difficult to migrate it to v3.x? Because in that case I don't know if it's worth investing effort

<baris>

If you are starting a new theme I would advise targeting nodebb 3.x because nodebb 2.x uses bootstrap3 and we are upgrading to bootstrap 5 in 3.x.

Joaquin Decima

Sure, but currently the forum where I want to use it is in nodebb v2.x and I don't know when I'll be able to upgrade to v3 (I tried locally but couldn't)

<baris>

If they have no plans to upgrade to nodebb 3.x near term then it's fine to stick to 2.x

Joaquin Decima

I would really like to use nodebb v3 but the upgrade process doesn't work. I don't know when it will be stable.

What errors are you seeing?

Joaquin Decima

When I change branches to 3 alpha it doesn't merge and the manual merge is complex because I don't know all the code (I'm using rebase)

julian

That suggests that you modified the core code, so you'll have to either merge the code yourself, or abandon it by running the appropriate git commands:

git reset --hard HEAD  # to get back to latest on your branch
git fetch 
git checkout bootstrap5 
git reset --hard origin/bootstrap5   # just in case

Thanks!

I have already migrated the theme to scss and I will work it for bootstrap 5.3 (I will see to force it) So when I have news I will show them
