### Responsive Design

<CodeGroup>
  ```jsx Responsive Component theme={null}
  import React from 'react';

  const ResponsiveSample = () => {
    const isMobile = useMediaQuery('(max-width: 768px)');
    const isTablet = useMediaQuery('(min-width: 769px) and (max-width: 1024px)');
    const isDesktop = useMediaQuery('(min-width: 1025px)');

    return (
      <div className={`responsive-container ${isMobile ? 'mobile' : ''}`}>
        <div className="grid">
          <div className="grid-item">
            <h3>Responsive Grid Item</h3>
            <p>This content adapts to different screen sizes.</p>
          </div>
          <div className="grid-item">
            <h3>Adaptive Layout</h3>
            <p>Layout changes based on device type.</p>
          </div>
          {isDesktop && (
            <div className="grid-item">
              <h3>Desktop Only</h3>
              <p>This content only appears on desktop devices.</p>
            </div>
          )}
        </div>
      </div>
    );
  };
  ```

  ```css Responsive Styles theme={null}
  .responsive-container {
    padding: 1rem;
  }

  .grid {
    display: grid;
    gap: 1rem;
  }

  .grid-item {
    padding: 1rem;
    background: white;
    border-radius: 8px;
    box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1);
  }

  /* Mobile styles */
  @media (max-width: 768px) {
    .grid {
      grid-template-columns: 1fr;
    }
    
    .responsive-container {
      padding: 0.5rem;
    }
  }

  /* Tablet styles */
  @media (min-width: 769px) and (max-width: 1024px) {
    .grid {
      grid-template-columns: repeat(2, 1fr);
    }
  }

  /* Desktop styles */
  @media (min-width: 1025px) {
