:::takeaways
- The `viewBox` attribute is the foundation of responsive SVG -- it defines an internal coordinate system that scales to any container
- Remove fixed `width`/`height` and use `width: 100%; height: auto` in CSS for fluid SVG scaling
- `preserveAspectRatio` controls whether SVGs center-fit (meet), crop-fill (slice), or stretch (none)
- Use CSS `clamp()` and container queries for icons and logos that scale smoothly across breakpoints
- `vector-effect: non-scaling-stroke` prevents stroke lines from becoming invisible at small sizes

## Why Responsive SVGs Matter

SVGs are inherently scalable, but making them truly responsive requires understanding how browsers render them and how CSS affects their behavior. This guide covers everything you need for perfect scaling.

## SVG Sizing Fundamentals

### The ViewBox Attribute

Critical for responsiveness:
```html
<svg viewBox="0 0 100 100">
  <!-- content -->
</svg>
```

ViewBox components:
- min-x: Left edge
- min-y: Top edge
- width: Coordinate width
- height: Coordinate height

### Width and Height

Interplay with viewBox:
```html
<!-- Fixed size -->
<svg width="200" height="200" viewBox="0 0 100 100">

<!-- Responsive (no dimensions) -->
<svg viewBox="0 0 100 100">

<!-- Percentage-based -->
<svg width="100%" viewBox="0 0 100 100">
```

### PreserveAspectRatio

Control scaling behavior:
```html
<!-- Default: center and fit -->
preserveAspectRatio="xMidYMid meet"

<!-- Fill container (may crop) -->
preserveAspectRatio="xMidYMid slice"

<!-- No preservation (stretch) -->
preserveAspectRatio="none"
```

:::tip
When you want an SVG to behave like a CSS `background-size: cover` image, use `preserveAspectRatio="xMidYMid slice"`. For `background-size: contain` behavior, use the default `xMidYMid meet`.

## CSS Sizing Strategies

### Fluid SVGs

Maximum flexibility:
```css
svg {
  width: 100%;
  height: auto;
}
```

### Container-Based Sizing

Control through parent:
```css
.svg-container {
  width: 50vw;
  max-width: 500px;
}

.svg-container svg {
  width: 100%;
  height: auto;
}
```

### Aspect Ratio Control

Modern CSS approach:
```css
.svg-wrapper {
  aspect-ratio: 16 / 9;
  width: 100%;
}

.svg-wrapper svg {
  width: 100%;
  height: 100%;
}
```

## Responsive Patterns

### Hero Icons

Scaling icons with viewport:
```css
.hero-icon {
  width: clamp(40px, 10vw, 120px);
  height: auto;
}
```

### Background SVGs

Full-width patterns:
```css
.hero {
  background-image: url('pattern.svg');
  background-size: cover;
  background-position: center;
}
```

### Inline SVGs

Responsive inline graphics:
```html
<div class="logo-container">
  <svg viewBox="0 0 200 50" class="responsive-logo">
    <!-- logo content -->
  </svg>
</div>

<style>
.responsive-logo {
  width: 100%;
  max-width: 200px;
  height: auto;
}
</style>
```

---

## Adaptive SVG Content

### Media Queries in SVG

Change content at breakpoints:
```html
<svg viewBox="0 0 100 100">
  <style>
    .detail { display: block; }

    @media (max-width: 400px) {
      .detail { display: none; }
    }
  </style>

  <circle class="main" cx="50" cy="50" r="40"/>
  <circle class="detail" cx="50" cy="50" r="10"/>
</svg>
```

### Switching SVG Content

Different files for breakpoints:
```html
<picture>
  <source srcset="logo-wide.svg" media="(min-width: 800px)">
  <source srcset="logo-compact.svg" media="(min-width: 400px)">
  <img src="logo-icon.svg" alt="Company Logo">
</picture>
```

### JavaScript-Based Adaptation

Dynamic content switching:
```javascript
function updateSVG() {
  const svg = document.querySelector('.adaptive-svg');
  const details = svg.querySelectorAll('.detail');

  if (window.innerWidth < 600) {
    details.forEach(el => el.style.display = 'none');
  } else {
    details.forEach(el => el.style.display = 'block');
  }
}

window.addEventListener('resize', updateSVG);
```

:::info
Media queries inside `<svg>` elements respond to the **SVG's own dimensions**, not the browser viewport. This means an SVG that's 300px wide in a 1200px viewport will trigger its `max-width: 400px` media query -- a powerful feature for component-level responsiveness.

## Icon Systems

### Responsive Icon Sizing

Consistent icon scaling:
```css
:root {
  --icon-sm: 16px;
  --icon-md: 24px;
  --icon-lg: 32px;
  --icon-xl: 48px;
}

.icon-sm { width: var(--icon-sm); height: var(--icon-sm); }
.icon-md { width: var(--icon-md); height: var(--icon-md); }
.icon-lg { width: var(--icon-lg); height: var(--icon-lg); }
.icon-xl { width: var(--icon-xl); height: var(--icon-xl); }
```

### Stroke Scaling

Prevent stroke thinning:
```css
svg {
  vector-effect: non-scaling-stroke;
}

/* Or in SVG */
<path vector-effect="non-scaling-stroke" d="..."/>
```

---

## Handling Edge Cases

### Preventing Overflow

Contain SVG content:
```css
svg {
  overflow: hidden;
}
```

### Minimum Sizes

Maintain legibility:
```css
.icon {
  min-width: 16px;
  min-height: 16px;
}
```

### Maximum Sizes

Prevent oversizing:
```css
.logo {
  width: 100%;
  max-width: 300px;
}
```

---

## Performance Considerations

### Complexity at Scale

Guidelines for performance:
- Simplify for small sizes
- Reduce nodes for mobile
- Use simpler versions where appropriate

### Loading Strategies

Optimize loading:
```html
<!-- Inline critical SVGs -->
<svg class="logo">...</svg>

<!-- Lazy load decorative -->
<img src="decoration.svg" loading="lazy">
```

## Testing Responsive SVGs

### Browser Testing

Check across:
- Chrome, Firefox, Safari, Edge
- Mobile browsers
- Different pixel densities

### Viewport Testing

Test at:
