# Mobile Layout Systems — Системы мобильной верстки

## 1. Mobile Grid Architecture

### Fluid Grid с Container Queries

```css
/* Container query grid — компонент знает свой размер */
.grid-container {
  container-type: inline-size;
  container-name: grid;
}

@container grid (min-width: 300px) {
  .grid {
    display: grid;
    grid-template-columns: 1fr;
    gap: 16px;
  }
}

@container grid (min-width: 600px) {
  .grid {
    grid-template-columns: 1fr 1fr;
    gap: 24px;
  }
}

@container grid (min-width: 900px) {
  .grid {
    grid-template-columns: repeat(3, 1fr);
    gap: 32px;
  }
}
```

### Mobile-First CSS Grid Pattern

```css
.mobile-grid {
  /* Mobile: single column */
  display: grid;
  grid-template-columns: 1fr;
  gap: 16px;
  padding: 0 16px;
}

/* Tablet landscape */
@media (min-width: 768px) {
  .mobile-grid {
    grid-template-columns: repeat(2, 1fr);
    gap: 24px;
    padding: 0 24px;
  }
}

/* Desktop */
@media (min-width: 1024px) {
  .mobile-grid {
    grid-template-columns: repeat(3, 1fr);
    gap: 32px;
    max-width: 1200px;
    margin: 0 auto;
    padding: 0 32px;
  }
}
```

## 2. Mobile Layout Patterns

### 2.1 Single-Column Stack (Mobile Base)

Основной паттерн для мобильных — контент идет вертикально.

```css
.mobile-stack {
  display: flex;
  flex-direction: column;
  gap: 24px;
  padding: 20px 16px 100px; /* 100px bottom для sticky CTA */
}

.mobile-stack .section {
  width: 100%;
}
```

**Применение:** Главная страница лендинга, product pages, blog posts.

### 2.2 Full-Bleed Hero (Mobile)

На мобайле hero часто занимает весь экран.

```css
.mobile-hero {
  height: 100dvh; /* dynamic viewport height */
  display: flex;
  flex-direction: column;
  justify-content: flex-end;
  align-items: center;
  padding: 24px;
  padding-bottom: calc(var(--safe-bottom) + 24px);
  text-align: center;
}

.mobile-hero__title {
  font-size: clamp(2rem, 8vw, 4rem);
  line-height: 1.1;
  margin-bottom: 16px;
}

.mobile-hero__subtitle {
  font-size: clamp(1rem, 4vw, 1.25rem);
  color: var(--text-secondary);
  margin-bottom: 24px;
  max-width: 600px;
}
```

### 2.3 Card Stack (Mobile Feed)

Классический паттерн соцсетей и маркетплейсов.

```css
.card-stack {
  display: flex;
  flex-direction: column;
  gap: 16px;
  padding: 16px;
  padding-bottom: calc(var(--safe-bottom) + 80px);
}

.card-stack .card {
  background: var(--surface-1);
  border-radius: 12px;
  overflow: hidden;
  box-shadow: 0 1px 3px rgba(0,0,0,0.08);
}

.card-stack .card__image {
  width: 100%;
  aspect-ratio: 16/9;
  object-fit: cover;
}

.card-stack .card__content {
  padding: 16px;
}
```

### 2.4 Swipeable Carousel (Mobile)

```css
.swipe-carousel {
  display: flex;
  gap: 16px;
  overflow-x: auto;
  scroll-snap-type: x mandatory;
  scroll-behavior: smooth;
  padding: 0 16px 16px;
  -webkit-overflow-scrolling: touch;
  scrollbar-width: none;
}

.swipe-carousel::-webkit-scrollbar {
  display: none;
}

.swipe-carousel .carousel-item {
  scroll-snap-align: start;
  flex: 0 0 auto;
  width: min(280px, 85vw);
}

/* Pagination dots */
.carousel-dots {
  display: flex;
  justify-content: center;
  gap: 8px;
  padding: 16px;
}

.carousel-dot {
  width: 8px;
  height: 8px;
  border-radius: 50%;
  background: var(--text-secondary);
  opacity: 0.4;
  transition: opacity 0.2s, transform 0.2s;
}

.carousel-dot.active {
  opacity: 1;
  transform: scale(1.3);
  background: var(--primary);
}
```

### 2.5 Split Screen (Tablet/Desktop)

```css
.split-screen {
  display: flex;
  flex-direction: column;
}

.split-screen .split-content,
.split-screen .split-media {
  flex: 1;
  padding: 24px 16px;
}

.split-screen .split-media {
  order: -1; /* media first on mobile */
}

@media (min-width: 768px) {
  .split-screen {
    flex-direction: row;
  }
  
  .split-screen .split-content,
  .split-screen .split-media {
    flex: 0 0 50%;
    padding: 48px 32px;
  }
  
  .split-screen .split-media {
    order: 1; /* media right on desktop */
  }
}
```

### 2.6 Off-Canvas Navigation

```css
.offcanvas-nav {
  position: fixed;
  top: 0;
  left: 0;
  width: 85vw;
  max-width: 320px;
  height: 100dvh;
  background: var(--surface-1);
  transform: translateX(-100%);
  transition: transform 0.3s ease;
  z-index: 1000;
  padding: 24px;
  padding-top: calc(24px + var(--safe-top));
}

.offcanvas-nav.open {
  transform: translateX(0);
}

.offcanvas-nav__overlay {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(0,0,0,0.5);
  opacity: 0;
  visibility: hidden;
  transition: opacity 0.3s ease;
  z-index: 999;
}

.offcanvas-nav.open + .offcanvas-nav__overlay {
  opacity: 1;
  visibility: visible;
}
```

### 2.7 Bottom Sheet Pattern

```css
.bottom-sheet {
  position: fixed;
  bottom: 0;
  left: 0;
  right: 0;
  background: var(--surface-1);
  border-radius: 16px 16px 0 0;
  transform: translateY(100%);
  transition: transform 0.3s ease;
  z-index: 1000;
  padding: 16px;
  padding-bottom: calc(16px + var(--safe-bottom));
  max-height: 80dvh;
  overflow-y: auto;
}

.bottom-sheet.open {
  transform: translateY(0);
}

.bottom-sheet__handle {
  width: 40px;
  height: 4px;
  background: var(--border-1);
  border-radius: 2px;
  margin: 0 auto 16px;
}
```

### 2.8 Floating Action Button (FAB)

```css
.fab {
  position: fixed;
  bottom: calc(var(--safe-bottom) + 24px);
  right: 24px;
  width: 56px;
  height: 56px;
  border-radius: 50%;
  background: var(--primary);
  color: white;
  display: flex;
  align-items: center;
  justify-content: center;
  box-shadow: 0 4px 12px rgba(0,0,0,0.3);
  z-index: 100;
  border: none;
  cursor: pointer;
  transition: transform 0.2s ease, box-shadow 0.2s ease;
}

.fab:active {
  transform: scale(0.9);
}
```

## 3. Mobile Typography & Spacing System

### Fluid Typography

```css
:root {
  /* Clamp-based fluid type scale */
  --text-xs: clamp(0.75rem, 0.7rem + 0.25vw, 0.875rem);
  --text-sm: clamp(0.875rem, 0.8rem + 0.3vw, 1rem);
  --text-base: clamp(1rem, 0.9rem + 0.5vw, 1.125rem);
  --text-lg: clamp(1.125rem, 1rem + 0.6vw, 1.25rem);
  --text-xl: clamp(1.25rem, 1.1rem + 0.75vw, 1.5rem);
  --text-2xl: clamp(1.5rem, 1.2rem + 1.5vw, 2rem);
  --text-3xl: clamp(1.875rem, 1.4rem + 2.3vw, 2.5rem);
  --text-4xl: clamp(2.25rem, 1.6rem + 3.25vw, 3rem);
}
```

### Mobile Spacing Scale

```css
:root {
  --space-xs: 4px;
  --space-sm: 8px;
  --space-md: 16px;
  --space-lg: 24px;
  --space-xl: 32px;
  --space-2xl: 48px;
  --space-3xl: 64px;
}
```

## 4. Mobile Component Patterns

### Mobile Navigation Bar (Bottom Tab)

```css
.bottom-nav {
  position: fixed;
  bottom: 0;
  left: 0;
  right: 0;
  height: calc(56px + var(--safe-bottom));
  padding-bottom: var(--safe-bottom);
  background: var(--surface-1);
  border-top: 1px solid var(--border-1);
  display: flex;
  justify-content: space-around;
  align-items: center;
  z-index: 100;
}

.bottom-nav__item {
  display: flex;
  flex-direction: column;
  align-items: center;
  gap: 4px;
  padding: 8px 16px;
  color: var(--text-secondary);
  text-decoration: none;
  font-size: 12px;
  transition: color 0.2s;
}

.bottom-nav__item.active {
  color: var(--primary);
}

.bottom-nav__icon {
  width: 24px;
  height: 24px;
}
```

### Mobile Card

```css
.mobile-card {
  background: var(--surface-1);
  border-radius: 12px;
  overflow: hidden;
  box-shadow: 0 1px 3px rgba(0,0,0,0.08);
}

.mobile-card__image {
  width: 100%;
  aspect-ratio: 16/9;
  object-fit: cover;
}

.mobile-card__content {
  padding: 16px;
}

.mobile-card__title {
  font-size: var(--text-lg);
  font-weight: 600;
  margin-bottom: 8px;
}

.mobile-card__meta {
  font-size: var(--text-sm);
  color: var(--text-secondary);
  margin-bottom: 12px;
}
```

### Mobile Button

```css
.mobile-button {
  min-height: 48px;
  padding: 12px 24px;
  border-radius: 8px;
  font-size: var(--text-base);
  font-weight: 600;
  display: inline-flex;
  align-items: center;
  justify-content: center;
  gap: 8px;
  border: none;
  cursor: pointer;
  transition: background 0.2s, transform 0.1s;
  -webkit-tap-highlight-color: transparent;
}

.mobile-button:active {
  transform: scale(0.98);
}

.mobile-button--primary {
  background: var(--primary);
  color: white;
}

.mobile-button--secondary {
  background: var(--surface-2);
  color: var(--text-primary);
}

.mobile-button--ghost {
  background: transparent;
  color: var(--primary);
}
```

## 5. Mobile Performance Optimization

### Image Optimization Pattern

```html
<picture>
  <source srcset="image-480.webp 480w, image-800.webp 800w, image-1200.webp 1200w"
          media="(min-width: 768px)">
  <img
    src="image-480.webp"
    loading="lazy"
    decoding="async"
    width="800"
    height="600"
    alt="Description"
    class="lazy-image"
  >
</picture>
```

### CSS Optimization

```css
/* Mobile-first critical CSS (inlined in <head>) */
/* Target: < 14KB gzipped for mobile LCP */

@layer mobile, tablet, desktop;
```

### Lazy Loading Pattern

```javascript
const lazyImages = document.querySelectorAll('.lazy-image');
const lazyObserver = new IntersectionObserver((entries) => {
  entries.forEach(entry => {
    if (entry.isIntersecting) {
      const img = entry.target;
      img.src = img.dataset.src || img.src;
      img.classList.add('loaded');
      lazyObserver.unobserve(img);
    }
  });
}, {
  rootMargin: '200px 0px',
  threshold: 0.01
});

lazyImages.forEach(img => lazyObserver.observe(img));
```
