How to perform Code splitting with CommonsChunkPlugin

Question

This is my current bundle information which i got from bundle analyzer plugin,

Current bundle information

I want to move the jquery to a separate chunk and extract css into a separate single css bundle, is there any other optimization which i can do to reduce my bundle size?

My current webpack is this webpack.base.js

   /**

   webpack loader authors not users):
