Yes, it is...
Não funciona, estão não perca seu tempo.
This is good, but it would be really useful if it also showed ONLY the used CSS, so we could just copy paste it.
Of course any such tool requires manual review and application, but it's unbeatable for examining an SPA for unused / duplicate CSS.
why dont remove?
not works
It flagged many classes as unused that actually were being used. Wasted two hours of my time
useless, doesn't work
actually works really well, and tells you about the usage of your css classes across an entire domain if you want it to. (does require you to open all the pages manually) but that aside ; great tool.
нет возможности сохранить только используемые стили
doesn't work!
Waste of time, its just do what chrome developer tools can do.
It shows the same information that can be gotten from Chrome dev tools. What would have made it useful is if it showed all used CSS that can be just copied and pasted over the old css file to quickly see if it missed anything. Right now it is pretty much useless unless developer improves on this foundation.
Works great, simple and clear feedback, would recommend
