A similar question was already posted here but, I think looking at the raw html, we will be able to better determine the required css than what Purgecss does.

PurgeCss

Webpack minifies JS and CSS files by default when we build them in production mode. But it does not remove useless styles or classes. For this, you can use libraries like https://purgecss.com/ Do not forget to check the dependency, connect only the functionality that you use.

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.

If you’re hand-crafting your CSS, using only the exact classes you need, you’ll still probably find that your CSS file size grows as your site does. But it doesn’t need to grow too much — you can remove unused classes with tools like Purge CSS .

PurgeCSS analyzes your HTML and internally keeps track of which selectors are being used or not. PurgeCSS actually analyzes other types of files besides HTML for selectors, such as template files and JavaScript. This feature is what makes PurgeCSS different from a similar solution, UnCSS, and related to a 'predecessor' solution called PurifyCSS. More on both of those later on.
