Fantastic. I've tried all of the extensions on the store which do this, but this is by far the best. I hope you keep up the development for this and not fade away like a lot of others devs! =]
Excellent. Cannot develop without it.
Incredible! Everything I was searching for, runs Live so you dont have to run every time you edit something,very nice suggestions while typing and other small features like colors are displayed in squares while typing names. The one of the best features is auto enable on websites. I have made dark theme mode for some websites, thanks to this extension! Awesome!!!
I can't live without it anymore.
great app but doesn't work with firebase.google.com
much lighter than stylish, and the same useful
Absolutely amazing! Love this tool so much! Great job!
On ne ne peut pas éditer les fichiers html locaux, mais appart ça l'extension est extrêmement utile et très bien réalisée. Je l'utilise depuis au moins un an je crois, et je n'ai jamais eu aucun problème. Elle sauvegarde très bien le css quand on quitte la page et l'interface est très intuitive.
Sometimes is useful, but not always...
Классное расширение, рекомендую.
