1. Responsive Layout Audit

✅ Viewport Support

Key Layout Improvements

Dashboard Page (/)

3. Component Mobile Variants

✅ DataTable Component

File: /src/components/ui/data-table.tsx

Mobile Improvements:

1. Card View (< 640px)

</div>

After:

<!-- Desktop: Table -->
<div className="hidden sm:block overflow-x-auto">
  <Table>...</Table>
</div>

<!-- Mobile: Cards -->
<div className="sm:hidden space-y-3">
  {rows.map(row => (
    <div className="rounded-lg border p-4">
      {/* Key-value pairs */}
    </div>
  ))}
</div>

✅ Forms

All form inputs now use:

8. Mobile-First CSS

✅ Breakpoint Strategy

All Tailwind classes follow mobile-first approach:

// ✅ CORRECT - Mobile first
<div className="text-sm sm:text-base lg:text-lg">

// ❌ WRONG - Desktop first
<div className="text-lg md:text-base sm:text-sm">

✅ Responsive Patterns

Grid Layouts:

// 1 column mobile, 2 on tablet, 3 on desktop
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4">

Spacing:

// Smaller on mobile, larger on desktop
<div className="p-4 sm:p-6 lg:p-8">
<div className="gap-3 sm:gap-4 lg:gap-6">

Typography:

// Responsive heading
<h1 className="text-3xl/tight sm:text-4xl/tight lg:text-6xl/tight">

// Responsive body text
<p className="text-sm sm:text-base lg:text-lg">

✅ Hidden Elements

Mobile-only:

<div className="lg:hidden">Bottom Nav</div>

Desktop-only:

<div className="hidden lg:block">Sidebar</div>

Tablet and above:

<div className="hidden sm:block">Extra info</div>
