Remove unwanted css & js file on Blogger , Blogspot? As: widgets.js and  css_bundle_v2.css. I want to create a blogspot theme from scratch. I have finished creating the basic structure of the theme.

Then I open my blog. I see in Chrome DevTools there are CSS and Javascript files that I do not know where it comes from.

My question is, where did the file come from? can I delete from my blog?
