              option = {
                enable_on = {
                  "html",
                }, -- set the file types you want the plugin to work on
                file_extensions = { "css", "sass", "less" }, -- set the local filetypes from which you want to derive classes
                style_sheets = {
                  -- example of remote styles, only css no js for now
                  "https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css",
