lừa đảo không thấy cái gì cả.
I've been using this tool for years and I'm pleased to leave a review that it saves me time and gives me comfort when modifying a page css before applying it on my websites. I appreciate the development of this extension.
Fantastic, good tool to fix broken sites like youtube without having to go in to devtools each time
would be gerat to detect diferent css automatically, like when satrt typing "center" you get all the existing options for fast css adjustments or testing
A great extension for live CSS customization — simple, efficient, and easy to use. I really like it!
Very good extention. Simple and effective.
Amazing tool!
Fantástica! La uso no solo para desarrollar software de FrontEnd sino también para ocultar elementos indeseables de las webs a las que suelo acudir. Un 10!
This one is the best. THE only editor I've found that you can move around! So many other extensions get in the way of styling because you can't move them around. :-)
awesome for fixing poor css on websites
