Can't print with style

Hi!

I'm sorry because I'm pretty sure you've already answered to that question many times but even when I check all topics, I can't solve my problem.

I explain :

I'm using Wordpress > Elementor & Formidable (to get the context).

Inside my Formidable view (Html), I put a button to print my nutritional values but I can't embed CSS with it, I tried to use `targetStyles: ['*']` but nothing works, everytime my print window is ugly.

This is what I want to print (without the print button)

This is what I get :

Here the code I inserted : `Imprimer` ([50] is a variable of formidable)

I have correctly imported css and js files inside the head tag :

Please, does anyone has a solution for me ? (I can't use external CSS file on my wordpress, all is merged and managed by wordpress).

Thanks a lot!
