This is the first extension I've seen that uses Manifest V3 that can change fonts in a website. Bravo. I might actually use this in a later point of time. Also, is it possible to use fonts locally? I have fonts that aren't hosted in Google Fonts, and I wonder if I can get them to work

Hello, is it possible to change the css of a specific part of the entire website you are on? That is, if you are on a newspaper website, change the style only of a headline that you select
