I searched for a long time but couldn't find the official document and media.

If you are using Tailwind v4, you shouldn't need a tailwind.config.js file. Configuration is done in CSS.

In Tailwind v4, you don’t usually need a tailwind.config.js file configuration happens right inside your CSS.

Even in v4, not everything is convenient to configure in CSS. For example we use the tailwind.config.js for typography plugin, where we disable generating some properties or even whole selectors (using null).

@software-based-boy In v4, the configuration has to be loaded via @config directive.
