Why Would I Add Code to Bottom of TIMBER.SCSS File Rather than THEME.SCSS File ? Minimal Theme

[Beyblade-Gamer]

I am using the Shopify Minimal Theme.

I am curious about something:

What is the Difference Between the "theme.scss.liquid" file, and the "timber.scss.liquid" file?

Almost all of the code that I have edited and added to the bottom, has been in the "theme.scss.liquid" file.

But there is ONE piece of code that I placed at the bottom of the "timber.scss.liquid" file.

Here is the code that I put in the bottom of timber.scss.liquid:

.header-bar{

font-size: 18px !important;

}

I only put it in the timber.scss file because that is where it said to put it, in the post that I read here.

Would it work if I put that SAME EXACT CODE in my "theme.scss.liquid" file instead (then removed it from timber.scss after)  ?????

I would rather not even deal with the timber.scss file, especially for just ONE piece of code (especially when I have so much other SIMILAR code in my theme.scss file).
