But is it good to generate the CSS?

Our question is based on the following information:
“WPBakery CSS file is huge and due to the fact that we are not using 99% them on our demo versions we suggest you to generate a CSS file without them. Check all elements and see which ones you are using and which not. It may decrease your page size by 200-400 KB.”
