Error: Tailwindcss not working in storybook

Question

I use webpack5, typescript, tailwindcss and storybook to make an Button UI component, I modify the example code from storybook to tailwindcss Here is the css code:

@tailwind base;
@tailwind components;
@tailwind utilities;

@layer components {
.storybook-button {
  @apply font-sans font-bold border-none rounded-3xl cursor-pointer inline-block leading-3;
}
.storybook-button--primary {
  @apply text-white bg-[#1ea7fd];
}
.storybook-button--secondary {
  @apply text-[#333] bg-[]
  color: #333 bg-transparent shadow-cyan-500/50;
}
.storybook-button--small {
  @apply text-xs px-4 py-2;
}
.storybook-button--medium {
  @apply text-sm px-5 py-3;
}
.storybook-button--large {
  @apply text-base px-6 py-3;
} 
}

But when I run yarn storybook, this css file is not working Button in storybook with tailwindcss
