the best app for web devalopment i give 10 stars if is a way to import sass from file to import the mixns and the variables
Лучшее из лучших! Абсолютный лидер. Best!!!
Very robust and has every feature I'd want in a live css editor. Well done. Love that it integrates SASS as well and also gives a pretty well done element finder. That said, I do not like that it floats. I have constant issues highlighting/copying/pasting. I also do not like how you resize it (only in the lower-right). I would love a slideout pane that you can resize and also move to the left or right side with an arrow vs. the floating box. My frustration is constant with both of these issues, especially since I use this extension on a Surface and when the resolution changes (from docking/undocking) I always need to resize, etc.
Best extension! I already tried many in the past, but none of them have been so simple and useful. - Element selector - Less/Sass compilers - autocompletion Fun to work with! Many thanks!!!
Great extension!. Please support live jQuery injection.
An amazing. +1 star for code beautify.
Impresionante!
This addon is great! Please support SASS (SCSS syntax). That would be great.
Great tool, but have had recent issues with its function, copy/paste problems, today could not edit.
after update - 5 stars
