Vim for frontend dev

I want to use vim as my text editor to frontend development. Anyone knows how to use live.js or any watch (reload mode) at vim? So I can refresh the page and I see how my CSS is going?

You can install tmux, a multiplexer. This is the setup I use for frontend.
It has a learning curve, but you won’t look back afterwards.
