How to style icons?

Question

css

Hello, I need icons for the site, but I don't want to download entire fonts/libraries. I just need a maximum of 10 - 15 icons. I don't want to write CSS myself, because with my practice it's better not to do this... What micro-nano libraries do you know for including icons, and perhaps even for including downloaded icons? If you yourself wrote something similar, I ask for a link to the github.
Thank you!
