RewriteRule page/([0-9]+)$ page.php?id=$1
It works, but the included links like css or js don’t work. page/ is seen like a folder, so the links (example: <link rel="stylesheet" type="text/css" media="screen" href="css/default.css" />) aren’t found.
Another example: if “id” doesn’t exist i do this ErrorDocument 403 /notfound.php, but you are redirected to domain.com/page/notfound.php. How i can solve this problem?
Try this instead :
This will redirect only if the requested file or directory does not realy exists.

Edit :
As for you issue with resources not beeing found, you will have to add the base tag to you head section in you html page :
