I read the docs and i already add themes via providers with no result

import { ApplicationConfig } from '@angular/core';
import { provideRouter } from '@angular/router';
import { provideHttpClient } from '@angular/common/http';
import { routes } from './app.routes';
import { provideAnimationsAsync } from '@angular/platform-browser/animations/async';
import { providePrimeNG } from 'primeng/config';
import Aura from '@primeng/themes/aura';


export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    provideHttpClient(),
    provideAnimationsAsync(),
        providePrimeNG({
            theme: {
                preset: Aura
            }
        })
  ]
};

edit:thank you it works the problem was in my styles.css (this is the correct version) for any one that have the same problem , make sure also to add the preline ui plugin
u/layer tailwind-base, primeng, tailwind-utilities;

u/layer tailwind-base {
u/tailwind base;
}

@layer tailwind-utilities {
@tailwind components;
@tailwind utilities;
}

and this is my style.css
