How we solve Unminified CSS Files
In our experience, unminified CSS files are stylesheets shipped with their original whitespace, comments, and formatting intact rather than run through a minification step that strips all non essential characters to reduce file size. This happens when a build process lacks a CSS minification step, commonly seen on sites without a modern bundler like Webpack, Vite, or a build tool plugin such as cssnano. Larger CSS payloads take longer to download and parse before the browser can begin rendering, which delays First Contentful Paint and Largest Contentful Paint.

Why this happens (and how we fix it)
In our experience, unminified CSS typically ships from sites without a modern build pipeline, meaning no Webpack, Vite, or PostCSS plugin like cssnano running a minification pass before deployment. Stylesheets get written and edited directly in their final, human readable form and pushed to production exactly as authored, with whitespace, comments, and formatting all still intact, which is especially common on sites maintained by editing theme files directly on the server rather than through a version controlled build process.
What it costs you while it goes unfixed
In our experience, every extra byte of whitespace and comment text in a render blocking CSS file adds download and parse time before the browser can construct the page's render tree, which delays First Contentful Paint and Largest Contentful Paint on every single page load. The fix is typically a one time build step, so the ongoing cost of leaving it unminified is a completely avoidable performance tax paid on every visit.
