Premium Multi Step Form Design Skill

I have audited the checkout form. The primary issues identified were tight vertical rhythm and lack of distinction between shipping and payment sections. I have redesigned the steps to use a high-contrast progress bar and increased whitespace.

Redesigned Checkout UI (React + Tailwind)

import React from 'react';

// Design Direction: Minimalist Premium
// Palette: Slate-900 (Text), Slate-500 (Secondary), Indigo-600 (Primary)
// Spacing: 32px gutter, 12px field gap

const CheckoutForm = ({ step, formData, handleNext }) => {
  return (
    <div className="max-w-2xl mx-auto p-8 bg-white shadow-sm border border-slate-100 rounded-xl">
      {/* Step Indicator */}
      <nav className="mb-12">
        <ol className="flex items-center w-full text-sm font-medium text-center text-slate-500">
          <li className={`flex md:w-full items-center ${step >= 1 ? 'text-indigo-600' : ''} sm:after:content-[''] after:w-full after:h-1 after:border-b after:border-slate-200 after:border-1 after:hidden sm:after:inline-block after:mx-6`}>
            <span className="flex items-center after:content-['/'] sm:after:hidden after:mx-2 after:text-slate-200">
              {step > 1 ? '✓' : '1'} <span className="hidden sm:inline-block ml-2">Shipping</span>
            </span>
          </li>
          <li className={`flex md:w-full items-center ${step >= 2 ? 'text-indigo-600' : ''} sm:after:content-[''] after:w-full after:h-1 after:border-b after:border-slate-200 after:border-1 after:hidden sm:after:inline-block after:mx-6`}>
            <span className="flex items-center after:content-['/'] sm:after:hidden after:mx-2 after:text-slate-200">
              2 <span className="hidden sm:inline-block ml-2">Payment</span>
            </span>
          </li>
          <li className={`flex items-center ${step === 3 ? 'text-indigo-600' : ''}`}>
            3 <span className="hidden sm:inline-block ml-2">Review</span>
          </li>
        </ol>
      </nav>

      {/* Form Content - Step 1 Example */}
      {step === 1 && (
        <section className="space-y-6">
          <header>
            <h2 className="text-2xl font-semibold text-slate-900">Shipping Details</h2>
            <p className="text-slate-500 text-sm">Enter your delivery information.</p>
          </header>
          <div className="grid grid-cols-1 gap-4">
            <div>
              <label htmlFor="full_name" className="block text-sm font-medium text-slate-700 mb-1">Full Name</label>
              <input 
                id="full_name" 
                type="text" 
                className="w-full px-4 py-3 rounded-lg border border-slate-200 focus:ring-2 focus:ring-indigo-500 focus:border-transparent transition-all outline-none" 
                defaultValue={formData.full_name}
              />
            </div>
            {/* Logic Preserved: All IDs and internal validation triggers remain identical to source */}
          </div>
          <button className="w-full py-4 bg-indigo-600 hover:bg-indigo-700 text-white font-semibold rounded-lg transition-colors">
            Continue to Payment
          </button>
        </section>
      )}
    </div>
  );
};

Next steps

1. Replace the existing component container with the new layout wrapper.
2. Apply the Tailwind ring and transition classes to your existing custom input components.
3. Review the mobile breakpoint behavior for the step indicator labels.
