How to create a multi color border with tailwind or CSS?

Question

How can I create a multi-colored border like the image below?

Currently, I'm working in Tailwind. It would be better if it were possible in Tailwind.

I tried with gradient and nothing match my requirement

Answer 1

Finally, this works for me! with CSS borders

    .custom-border {
      border-image: linear-gradient(to right,
