Is it possible to create a child theme from a parent theme like “simple”? Like it is possible in Wordpress.
Definition of a child theme:
A child theme is a theme that inherits the functionality and styling of another theme, called the parent theme. Child themes are the recommended way of modifying an existing theme.
I searched on Google but didn’t find any information about creating a child theme for SilverStripe.
Looks right to me, SS will keep stepping through the list until it finds the file it needs, theoretically you can add as many themes as you want (though I haven’t tried more than 3).
One thing of note, I don’t think you need to worry about composer.json for your custom theme, I think SSViewer simply looks inside the the “themes” folder for any folders matching the list of themes you provide to it (though I could be wrong).
