如何重新创建 Tailwind 背景过渡颜色？

Question

I saw the special color on https://tailwindcss.com/docs/transition-property in dark mode Here's the pic

I want to know how can I recreate this? With gradient color or other css property?

I tried to see how they did it by inspecting their css only found

--tw-bg-opacity: 1;
background-color: rgb(15 23 42/var(--tw-bg-opacity));

Which is only a background color.

If you know how to do this, please let me know. Thanks!

They implemented it by adding an image inside the body here is how they implemented it from the inspector

and here is the link for the image they have used: https://tailwindcss.com/_next/static/media/docs-dark@30.77f062b5fd90f0d2cd4752cd9a8649c8.avif
