I was going to write my own plugin but this solves my problem i just wanted to inject some CSS and maybe some JS into a page
It would be even better with Export/Import options!
Obliger de désactiver/réactiver à chaque fois l'extension pour qu'elle fonctionne.
excelente opción para paginas de uso frecuente que no tienen un buen contraste de colores.
awesome script it works well.
Класс! Можно редактировать темы для сайтов и делать тёмные!
Pretty good functionality, if not a little clunky to edit. One star down for exact domain name matching not allowing us to add CSS to pages based on custom domain name string searched inside domain string of page url. Like for example "oogle.com" matching: google.com, images.google.com, etc. I have made a custom version of this script which allows this by changing just one line inside the inject.js. It is still quite clunky to set up but now it allows me to be more flexible with custom CSS for domains and their subdomains. Please think about adding this to your extension, I'll be happy to give you a splendid 5-star review!
Simple and good. I do recommend.
just works
Мусор какой-то. Не меняет стили
