How to add script to PhpStorm to extract classes and id from html as css code?

Question

css

I found several scripts on GitHub that allow you to extract classes and IDs from an HTML file into CSS code. It is convenient to use such a converter directly in PhpStorm. I copy the HTML code or part of the code, paste it into the included CSS file and get the CSS code.
