Lastima que hoy 23 de Abril del 2024, esta extension ha dedajo de funcionar en CHROME!!!!!! Me ha servido mucho, pero ya no se puede usar mas... que bronca tengo!!
Primera vez que me tomo el tiempo para hacer una valoración, esta extensión lo merece, es excelente. Gracias por desarrollarla, es muy útil. ❤️
Makes the life easier! :D
Amazing!
Best
This is A LOT BETTER than using Stylus or Stylebot, I think it did exactly what I wanted it to do Mainly for me to practice css I really appreciate this thing exists because it was just really annoying to find out what would work best for me but I already really like it after using it for like 3 minutes because I place my code in just to see if it'd work and I love it. I'm going to tell other people about this extension it is really helpful and I'm probably gonna write in other reviews that is probably a better alternative then Stylebot or Stylus, they're either very complicated to use or they just don't work anymore for some reason. Thank you for making this and I'm glad I was able to stumble upon this.
good extentions
基本的に素晴らしい。 ただ、アンドロイドスマホにおいて、kiwiブラウザ上で使おうとしたら、styleのreapplyを自動で行うことができない。 どの様に権限を付与したらいいのか教えてほしい。
Really amazing! it's so much easier to make themes for websites with this!
Does not work at all.
