Change theme

[Mino7]

Hello, 

I want to change my free theme to another theme and I wonder to know if I have to change my code from scratch, because I made many changes on "theme.scss.liquid" or I can just copy and paste the code on my actual theme to the new one that I want to set up. 

Thank you.

Yes,

you can create changes to theme.scss

Thank you

And is that possible to make the single product shopify page as a default instead of having the product page given to the new theme ?

Create new css file on your new theme  call in on theme.liquid by  using below code

{{ 'mycss.css' | asset_url | stylesheet_tag }}

copy past all your old css in this file

Thanks, but I'm worry about the css selector on my old "theme.scss.liquid". I think that they're different from my new theme.

of course, they are different from each other.
