I have come to discover the superb Autoprefixer tool that adds all css prefixes to your css. Nice! See it here : https://github.com/postcss/autoprefixer
I also discoverd there was a symfony bundle to make it work under assetic. See it here : https://github.com/bit3/assetic-autoprefixer
unfortunately, I am developping with a PC running windows so I can't run "sudo something" to install autoprefixer: "sudo npm install -g autoprefixer"
Does anyone know how I could install autoprefixer on windows 7 ?
Thanks a lot!
