Examples

In Surface

When used inside a Surface component, use variant="secondary" on form controls (Input, TextArea, etc.) to apply the lower emphasis variant suitable for surface backgrounds.

Customization

Tailwind CSS

Global CSS

Use the @layer components directive to target Fieldset BEM-style classes.

@layer components {
  .fieldset {
    @apply gap-5 rounded-xl border border-border/60 bg-surface p-6 shadow-field;
  }

  .fieldset__legend {
    @apply text-lg font-semibold;
  }

  .fieldset__field_group {
    @apply gap-3 md:grid md:grid-cols-2;
  }

  .fieldset__actions {
    @apply flex justify-end gap-2 pt-2;
  }
}

Styling Reference

HeroUI follows the BEM methodology to ensure component variants and states are reusable and easy to customize.
