How to check if css and scss are correct?

Question

css

I made a website using scss. After a while, you need to tie it up again. You can of course use a css file and that's it. But I'm really wondering how to check if css changes have been made? Well, that is, if I start writing in scss right away, I convert it and all the changes that were made to css will disappear. Is there any way to check this?

Answer 1

Start checking from the date of the change. If the date SCSS and CSS are the same, then this is what you need.
If not, try compiling SCSS to another file, and then using any utility to compare with the old CSS
