3. Custom Theme Creation

/* Custom theme example */
@theme custom {
  @import 'default';

  section {
    background-color: #f8f9fa;
    font-family: 'Noto Sans JP', sans-serif;
  }

  h1 {
    color: #2c3e50;
    border-bottom: 3px solid #3498db;
  }

  code {
    background-color: #ecf0f1;
    padding: 0.2em 0.4em;
    border-radius: 3px;
  }
}

4. Layout Techniques

• Two-Column Layout:

  <div class="columns">
  <div>
  
  Left side content
  
  </div>
  <div>
  
  Right side content
  
  </div>
  </div>
  

• Background Image Usage:

  ![bg right:40%](image.jpg)
  

• Page Number Customization:

  <!-- _paginate: false -->
  

5. Animations and Transitions

• Smooth effects using CSS transitions
• Fragment display (partial reveal) implementation
• Visual continuity between slides

6. Code Display Optimization

```python
# Appropriate font size and line spacing
def calculate_complexity(n: int) -> int:
    """Time complexity: O(n log n)"""
    return n * math.log2(n)

### 7. Accessibility Considerations
