How to make a stub on a Codeigniter website?

Question

CodeIgniter

Hello everyone, we need to close the site built with Codeigniter for the period of reconstruction. I made a stub, in .htaccess from the very beginning I have such lines
RewriteEngine On
RewriteBase /
RewriteRule ^.* coming-soon.php [L]
It connects, but it doesn’t pick up styles, just like pictures, pictures and styles folders are in the root, in the same place as the file with a stub, I have such a path to the styles, I tried it and
I ask for help, thanks in advance

Answer 1

Make a redirect not from any address to coming-soon.php, but only from addresses ending in .php
