hi,
i’m trying fo install multisite, it works very well, i need only plugins in the main website, but my issue is to have different css for each subsite

i try Inheritance but with no success. Thanks for any tips

my folder structure :

root
setup.php
   >user
      >themes
         >MainTheme
            >template
            >css
            >blueprints
            > etc...
      >sites
         >themes
            >subsite A
               >config
               >pages
               >themes
                  >MainTheme 
                     >css
                        - custom.css
            >subsite B

My setup.php
— php
use Grav\Common\Filesystem\Folder;

// Get relative path from Grav root.
$path = isset($_SERVER[‘PATH_INFO’])
? $_SERVER[‘PATH_INFO’]
: Folder::getRelativePath($_SERVER[‘REQUEST_URI’], ROOT_DIR);

// Extract name of subsite from path
$name = Folder::shift($path);
$folder = “sites/{$name}”;
$prefix = “/{$name}”;

if (!$name || !is_dir(ROOT_DIR . “user/{$folder}”)) {
return [];
}

// Prefix all pages with the name of the subsite
$container[‘pages’]->base($prefix);

$themes = [“user/themes”];
if (is_dir(DIR . “/user/sites/{$folder}/themes”)) {
array_unshift($themes, “user/sites/{$folder}/themes”);
}

return [
‘environment’ => $name,
‘streams’ => [
‘schemes’ => [
‘user’ => [
‘type’ => ‘ReadOnlyStream’,
‘prefixes’ => [
’’ => [“user/{$folder}”],
]
],
‘themes’ => [
‘type’ => ‘ReadOnlyStream’,
‘prefixes’ => [’’ => $themes]
],
]
]
];

ok i found it need to add to setup.php, so each subsite has his own css, but new issue appear with modular page i open a new thread

            'environment' => [
                'type' => 'ReadOnlyStream',
                'prefixes' => [
                    '' => ["user/{$folder}"],
                ]
            ],
