RewriteBase with WAMP not working (vhost) - mod-rewrite

Question

I have a problem, let me explain.
Rewrite_module is enabled on WAMP
My host is mapped:
127.0.0.1 localhost
127.0.0.1 mydomain.com
My vhost declared on WAMP:
<VirtualHost *: 80>
ServerAdmin contact#mydomain.com
DocumentRoot "E:/wamp/www/subfolder/"
ServerName mydomain.com
ErrorLog "logs/mydomain.com.log"
CustomLog "logs/mydomain.com.log" common
<Directory "E:/wamp/www/subfolder /">
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow, deny
Allow from all
</ Directory>
</ VirtualHost>
For now, no problem, mydomain.com arrives on E:/wamp/www/subfolder/
My projects are in sub folders such as E:/wamp/www/subfolder/my-project/
I have a htaccess with:
<Mod_rewrite.c IfModule>
RewriteEngine On
RewriteBase /my-project/
RewriteRule ^index\php$ - [L]
RewriteRule ^assets/css/(.*) /my-project/content/themes/assets/css/ $ 1 [QSA, L] [QSA, L]
RewriteCond% {REQUEST_FILENAME}! F
RewriteCond% {REQUEST_FILENAME}! -d
RewriteRule. /my-project/index.php [L]
</ IfModule>
My problem comes here. If I go on mydomain.com/my-project/ it comes to the site with no problem, but the css (for example) are not loaded, because the link is:
mydomain.com/content/themes/assets/css/
It should have:
mydomain.com/my-project/content/themes/assets/css/
I think the RewriteBase not working and I do not know why.
Thank you very much and sorry for my english.

I think you misunderstood the point of a Virtual Host.
You should create a Virtual Host for EACH of your projects so something like this
<VirtualHost *: 80>
ServerAdmin contact#mydomain.com
DocumentRoot "E:/wamp/www/subfolder/project1"
ServerName mydomain1.com
ErrorLog "logs/mydomain.com.log"
CustomLog "logs/mydomain.com.log" common
<Directory "E:/wamp/www/subfolder/project1">
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow, deny
Allow from all
</Directory>
</VirtualHost>
<VirtualHost *: 80>
ServerAdmin contact#mydomain.com
DocumentRoot "E:/wamp/www/subfolder/project2"
ServerName mydomain2.com
ErrorLog "logs/mydomain.com.log"
CustomLog "logs/mydomain.com.log" common
<Directory "E:/wamp/www/subfolder/project2">
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow, deny
Allow from all
</Directory>
</VirtualHost>
This makes each project look and react like it was a single website on its own unique Apache instance and makes moving your projects to live servers more reliable.
You also do not need a .htaccess now unless this one project actually requires it.
