Purifycss wordpressKazi

I have found this utility for optimizing CSS: I want to use this utility (purifycss) in my project, but my project is 100% Java. So I need a way to deploy this as a Java Servlet Filter or as a Maven Plug-in or a Spring MVC interceptor or ... (you suggest: something that runs in Java). Your task for this project, is to make this happen: how to use purifycss in any Java project. You can solve this problem in many different ways, provided your general approach pre-approved by the employer. The budget for this project is very small. Please bid low.

I'm trying to figure out what changes were made to a particular menu to make it responsive. I saved the page off, and edited the stuff out of the bottom. I cannot get node.js/purifycss to run on my system. I just need the results from this single page, which I will zip up and send to you. Freelancer doesn't allow me to state this specifically, but I have $30 budgeted for this job. (And if you know purifycss, it'll probably take you 10 minutes.) I just need to know the specific styles used in their version of the menu, so I can adapt those styles to our regular website.
