Reproduction

Sample Download Link

2. Observe the warning.

Describe your issue

Tailwind v3.0 deprecated the CLI's --purge option and replaced it with --content. That's fine, but it doesn't work. I get the following:

warn - The `content` option in your Tailwind CSS configuration is missing or empty.
warn - Configure your content sources or your generated CSS will be missing styles.
warn - https://tailwindcss.com/docs/content-configuration

The issue can indeed be solved by adding content to tailwind.config.js, but since the option still exists in the CLI, it should also be possible there. Important to note is that --purge using the CLI worked fine in v2.x. There is clearly a bug with the new replacement --content option.
