Theme customization - CSS best practices

[Jérémie32]

Hello,

 

My shop is running under 1.4.1 and I don't expect to succeed to migrate to latest 1.7 version.

Thus, I'm currently creating a new shop with the latest 1.7 version.

 

My objective is to maximize the easiness to upgrade in the future.

 

So far, I have created a child theme to manage .tpl customization.

 

I'm now wondering how to efficiently manage CSS.

 

What are the best practices or recommendations?

customize the theme.css or custom.css only?

from the parent theme or the child one?

 

I can imagine this is a question for any lazy developer.

 

Thanks for your feedback.

 

Best Regards,

Jérémie

You can't upgarde Prestashop from 1.4.x->1.7 (as the code/theme is different)

for css changes just make changes within your theme folder (child or parent theme is not important), because when you make upgrades in the fututure, the theme is still usable and all your code is saved
