Excluding JS/CSS files from rewriting

my htaccess has these directives inside of it.

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} \.(css|js)$
RewriteRule ^blog_show/(.*)$ blog_show.php/?t=$1 [NC,L]

the rewriting condition is for excluding css/js files from rewriting and it works.
The problem is the RewriteRule…it seems that is not happening at all…I have a 404 message from the server.

For example clicking this link:/blog_show/2016-07-25/an–offer, I get
the requested URL was not found on the server…no rewriting takes place.
