## Breakpoints Overview

The project uses **Tailwind CSS** with a **mobile-first** approach. The following breakpoints are defined in `tailwind.config.mjs`:

| Breakpoint | Min-Width | Description            | Common Devices                  |
|------------|-----------|------------------------|---------------------------------|
| (default)  | 0px       | Mobile base styles     | Small phones (320px+)           |
| `xs`       | 375px     | Small phones           | iPhone SE, older Androids       |
| `sm`       | 640px     | Large phones / phablets| iPhone 14, Galaxy S series      |
| `md`       | 768px     | Tablets                | iPad, Android tablets           |
| `lg`       | 1024px    | Desktop / large tablets| Laptops, iPad Pro landscape     |
| `xl`       | 1280px    | Large desktops         | Desktop monitors                |
| `2xl`      | 1536px    | Ultra-wide             | Wide monitors                   |

> **Note:** The `xs` breakpoint (375px) was added to `tailwind.config.mjs` to handle very small mobile devices gracefully.

## Page-by-Page Responsive Analysis

### 1. Homepage (`/`)

**Status: ✅ Fully Responsive**

| Section           | Mobile (320-639px)           | Tablet (768-1023px)       | Desktop (1024px+)           |
|-------------------|------------------------------|---------------------------|------------------------------|
| Hero              | Single col, fluid text       | Same layout               | Same layout, larger text     |
| Benefits          | 1-col grid                   | 2-col grid                | 4-col grid                   |
| Services          | 1-col grid                   | 2-col grid                | 2-col grid (max-w-6xl)       |
| How It Works      | 1-col grid                   | 2-col grid                | 4-col grid with connectors   |
| Stats             | 2-col grid                   | 2-col grid                | 4-col grid                   |
| Testimonials      | Single slide carousel        | Single slide carousel     | Single slide carousel        |
| FAQ               | Stacked (header + accordion) | Stacked                   | 2-col (sticky header)        |
| CTA               | Stacked buttons              | Inline buttons            | Inline buttons               |

**Key Patterns:**
- Hero text: `text-5xl sm:text-6xl lg:text-7xl xl:text-8xl` — fluid scaling
- CTA buttons: `flex flex-wrap justify-center gap-4` — wraps gracefully on small screens
- Tech logos: `flex flex-wrap justify-center items-center gap-12` — wraps on mobile

### 2. Services Page (`/services`)

**Status: ✅ Fully Responsive**

| Section           | Mobile (320-639px)           | Tablet (768-1023px)       | Desktop (1024px+)           |
|-------------------|------------------------------|---------------------------|------------------------------|
| Hero              | 1-col, fluid text            | Same                      | Same                         |
| Stats bar         | 2-col grid                   | 4-col grid                | 4-col grid                   |
| Service cards     | 1-col grid                   | 2-col grid                | 2-col grid                   |
| Service details   | Stacked (content/visual)     | Stacked                   | 2-col alternating layout     |
| Floating badge    | Hidden (`hidden sm:block`)   | Visible                   | Visible                      |
| Case studies      | 1-col grid                   | 2-col grid                | 3-col grid                   |
| Pricing           | 1-col stacked (no scale)     | 3-col, middle scaled      | 3-col, middle scaled 105%    |
| Process steps     | 1-col grid                   | 2-col grid                | 4-col with arrows            |

**Fix Applied (2026-03-21):**
- Pricing tier highlight: Changed `scale-105` → `md:scale-105`
- **Reason:** On mobile, the highlighted pricing card was causing horizontal overflow since the card occupies full width. The scale effect now only applies at `md` (768px+) where there's sufficient surrounding space.

### 3. Portfolio Page (`/portfolio`)

**Status: ✅ Fully Responsive**

| Section           | Mobile (320-639px)           | Tablet (768-1023px)       | Desktop (1024px+)           |
|-------------------|------------------------------|---------------------------|------------------------------|
| Hero              | 1-col, fluid text            | Same                      | Same                         |
| Stats bar         | 2-col grid                   | 4-col grid                | 4-col grid                   |
| Featured projects | 1-col stacked                | 1-col stacked             | 3-col (first spans 2 cols)  |
| Search bar        | Full-width, centered         | Full-width max-w-xl       | Full-width max-w-xl          |
| Filter tabs       | Flex-wrap, scrollable        | Flex-wrap, centered       | Flex-wrap, centered          |
| Project grid      | 1-col                        | 2-col                     | 3-col                        |
| Case study modal  | Full-width, stacked content  | Full-width                | max-w-5xl centered           |

**Modal Gallery Heights:**
- Gallery image: `h-64 sm:h-80 lg:h-96` — scales up on larger screens

### 4. Contact Page (`/contact`)

**Status: ✅ Fully Responsive**

| Section           | Mobile (320-639px)           | Tablet (768-1023px)       | Desktop (1024px+)           |
|-------------------|------------------------------|---------------------------|------------------------------|
| Hero              | 1-col text                   | Same                      | Same                         |
| Trust stats       | 2-col grid                   | 4-col grid                | 4-col grid                   |
| Form layout       | Stacked (form then sidebar)  | Stacked                   | 5-col split (3+2)            |
| Form fields       | 1-col fields                 | 2-col pairs (sm:grid-cols-2)| 2-col pairs                |
| Budget options    | Flex-wrap chips              | Flex-wrap chips           | Flex-wrap chips              |
| Contact info cards| 1-col → 2-col at xs (375px) | 2-col                     | 2-col                        |
| Map embed         | Full-width card              | Full-width card           | Full-width card              |
| Social links      | Full-width stacked           | Full-width stacked        | Full-width stacked           |
| FAQ accordion     | Full-width stacked           | Full-width max-w-3xl      | Full-width max-w-3xl         |

**Fix Applied (2026-03-21):**
- Contact info cards: Changed `grid-cols-2` → `grid-cols-1 xs:grid-cols-2`
- **Reason:** On very small screens (320px phones), 2 columns of contact cards with icons and text were cramped. Cards now stack at 1-column below 375px.

## Automated Testing

Playwright tests for responsive design are located in:
- `tests/cross-browser.spec.ts` — Cross-browser and viewport testing
- `tests/accessibility.spec.ts` — WCAG compliance at various viewports

Run responsive tests:
```bash
npx playwright test --grep "responsive"
```

---

## Known Issues / Notes

1. **Testimonial carousel on mobile**: The carousel uses 100% translateX transforms. On very small screens, touch swipe is not implemented (only button navigation). Future enhancement: add touch/swipe support.

2. **Portfolio tech filter panel**: When expanded, the technology filter pills use `flex flex-wrap` which can result in many rows on small screens. This is acceptable UX but could be improved with a dropdown on mobile.

3. **Services page visual illustrations**: The service detail "visual element" (decorative mock-up) uses `aspect-square`. On mobile this renders as a tall square. On very narrow screens (320px), this can be visually heavy. Consider adding `max-h-64 sm:aspect-square` for tighter control.

4. **Print styles**: No print-specific styles are defined. If print support is needed, add `@media print` rules.

---

## CSS Custom Properties for Responsive Spacing

```css
/* Defined in src/styles/global.css */
--section-padding: 6rem;     /* Desktop: py-24 */
--section-padding-sm: 4rem;  /* Mobile: py-16 */
--container-max: 80rem;      /* max-w-7xl */
```

These are referenced as Tailwind utilities (`.py-section`, `.py-section-sm`) throughout the site for consistent section spacing.
