If you use subcommunities on your forum but would like for each one to have its’ own look and feel, you can choose to build an individual theme for each one.
Most communities will start by creating a theme for their default community which will become the base theme for other subcommunities.
For more information on creating a new theme in foundation see this article:
Once you are happy with your base theme, you can copy it and make whatever edits are needed for another subcommunity without starting from scratch.
Applying a different version of your base theme to other subcommunities
Create a copy of your base Foundation Theme in your dashboard, if this version will be a tweaked version of your main theme. You may also select the Foundation out-of-the-box theme if you would like to start from scratch for a particular subcommunity:
You may want to name your copy something similar to the subcommunity so it’s easy to remember:
Customize the new theme copy to your liking and save.
Applying a different theme to a particular subcommunity
Add your new subcommunity in your dashboard (go to Settings, then Subcommunities at the left) and select the appropriate theme:
Hit save and you’re done!
Editing and Updating Themes
Once copied, a theme branches into its own file and edits to one theme will not affect another, even if it was copied from the one being edited. If you need to make a change that should apply to all themes, you will need to update each theme individually in the UX, or if you have technical resources, you can optionally update via the API.
To edit a non-default theme, click the three dots at the top right and select edit:
