How to setup .htaccess in YII2 for subdomain?

Question

Yii

Hey! Set up .htaccess for subdomain
# Backend redirect
RewriteCond %{REQUEST_URI} ^/backend
RewriteRule ^backend/(.*)$ backend/web/$1 [L]
# Statics redirect
RewriteCond %{REQUEST_URI} ^/statics
RewriteRule ^statics/(. *)$ statics/web/$1 [L]
# Frontend redirect
RewriteCond %{REQUEST_URI} ^(.*)$
RewriteRule ^(.*)$ frontend/web/$1
# Mobile redirect
RewriteCond %{HTTP_HOST} ^m\.site \.ru$
RewriteRule ^(.*)$ mobile/web/$1
When entering m.site.ru everything works, index.php and settings are taken from where it should be, BUT, assets, css, js does not work.
Please tell me how to set up .htaccess for assets, css, js for a subdomain.

A separate host is not easier?
