Tailwindcss v4 preset does not have a tailwind.config.js file, how do you recommend customizing it in this project?

[aboutjquery]

For example, setting the center container
In which file should I make these settings? In the past, I did it through tailwind.config.js. Now I want to change it. How can I use css first config in this project?

Should be /tailwind/tailwind.css? Could you give a simple example?

Thanks all

See the most recent release notes for clarification.

From what you're saying, I strongly suspect that you're looking for the ./tailwind/tailwind-theme.css file.

That said, it is also still possible to use files like tailwind.config.js, but I generally suggest following the recommended approach of the library itself, which is very much leaning into CSS-based configuration wherever possible. (The documented exception is a legacy plugin like Tailwind Typography.)
