style just by .css file?

[rocky-III]

Thanks for AOS !!!

I'm not that experienced with styling websites, so forgive me if my questions sounds not appropriate.

---

If all the aos css and js is loaded by the html header - is there a way to apply aos animations just by a separate .css file without touting the rest of the html code of a page?

So lets say we have html pages where widgets are styled by the class .widget - is there a way to add aos animations to .widget ?

Thanks
