  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(300px, 1fr));
  gap: 2rem;
  padding: 2rem;
}

.grid-item {
  background: #f8f9fa;
  padding: 1.5rem;
  border-radius: 8px;
  box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1);
}

  --border-radius: 8px;
  --spacing-unit: 1rem;
}

.button {
  background-color: var(--primary-color);
  border-radius: var(--border-radius);
  padding: calc(var(--spacing-unit) * 0.5) var(--spacing-unit);
}

  }
}
