Yes. The best way is to make the admin page CSS use theme variables, then define those variables differently in DSA.css and SpaceCommand.css.

That way the same Admin page automatically adapts based on whichever theme is loaded.

1. Add this shared Admin CSS
Put this in either:

text

Components/Pages/Admin.razor.css
or your global:

text

wwwroot/css/app.css
css
