Technical Details

CSS Variables (Mobile)

:root {
  --mobile-header-height: 60px;
  --mobile-nav-height: 64px;
  --mobile-padding: 1rem;
  --mobile-gap: 0.75rem;
}

Touch Target Hierarchy

/* Standard buttons */
button, a { min-height: 48px; min-width: 48px; }

/* Small actions */
.btn-sm { min-height: 40px; min-width: 40px; }

/* Extra small (icons) */
.btn-xs { min-height: 36px; min-width: 36px; }

Active State Pattern

button:active {
  transform: scale(0.95);
  opacity: 0.7;
}

Safe Area Handling

.chat-input-container {
  padding-bottom: calc(env(safe-area-inset-bottom) + 0.75rem);
}

Responsive Modal Pattern

@media (max-width: 768px) {
  .modal-content {
    position: fixed;
    inset: 0;
    border-radius: 0;
  }
}

Swipe Gesture Implementation

const onTouchStart = (e: React.TouchEvent) => {
  setTouchStart(e.targetTouches[0].clientX);
};

const onTouchMove = (e: React.TouchEvent) => {
  const currentTouch = e.targetTouches[0].clientX;
  setSwipeDistance(currentTouch - touchStart);
};

const onTouchEnd = () => {
  const distance = touchStart - touchEnd;
  if (Math.abs(distance) > threshold) {
    distance > 0 ? onSwipeLeft() : onSwipeRight();
  }
};

Pull-to-Refresh Pattern

const handleTouchMove = (e: React.TouchEvent) => {
  if (window.scrollY === 0) {
    const distance = e.touches[0].clientY - startY.current;
    setPullDistance(Math.min(distance, threshold * 1.5));
  }
};
