Please read #how-to-get-help . Ask a question (you didn't ask any), and provide a minimal reproduction as a stackblitz. In your question, tell precisely what you're doing, what you expect to happen, and what happens instead.

Your .car-list div doesn't have display flex.

I mean the div which has the css class car-list.

That's the whole point of providing a minimal reproduction. In such a minimal reproduction, you would only have kept the car list, because that's where the problem is. And you would thus have concentrated on the important stuff, and maybe even found the issue by yourself.
