Hi,

The "local" folder is for override purpose. In your case, you are adding new file, you don't need the local folder. You should create the custom.css file in the folder: templates\t3_bs3_blank\css\layouts (you have to create the "layouts" folder as it's not included by default). Once done, open the layout file you want to load the custom.css file and add the code:

<?php $this->addCss('layouts/custom') ?>

P/S: This will only work when dev mode is off as the site will use CSS in this case.

Regards.

Thank you for your reply.

I did what you propose, but He considers that one of the CSS files because I have 2 files, one for each layout. I wish that every call of a page, a particular CSS file is linked to it.

I'll try to be clearer:
I have a template with 2 styles, one per page. I use some of the same class in two files. I wish I could call the Class "red" in the CSS file when Red I view the page 1 and call the same Class "red" in the CSS file when "green" I view the page 2.

Yes, it actually works.
Thank you very much for your help

Great to see it work. Well done!
