   Remove unused CSS

   

   When I searched online I couldn't find an "industry standard" solution to this problem. What I ended up doing was using the popular tool PurgeCSS along with a quick Python script to generate the appropriate command. What the PurgeCSS tool does is search for all your HTML files, gather all the CSS classes used, and then "purge" all the unused ones from the CSS file. You just need to declare all the HTML files you have.

   This is almost a trivial task if you are working with a modern client-side JS framework. But if you are developing a web app using Django's template language with some CSS library (such as Bulma or Bootstrap), and potentially using HTMx for more dynamic behavior, this is not an easily solved problem.
