Animated Gradient Background

Что это

Анимированные градиентные фоны, которые плавно перетекают друг в друга. Один из ключевых паттернов Stripe.com и современных SaaS-лендингов. Создаёт ощущение "живого" дизайна.

Типы анимированных градиентов

1. Stripe-Style (shifting color flow)

.gradient-bg {
  background: linear-gradient(
    135deg,
    #6366f1,
    #8b5cf6,
    #ec4899,
    #f43f5e,
    #6366f1
  );
  background-size: 400% 400%;
  animation: gradient-shift 15s ease infinite;
}

@keyframes gradient-shift {
  0% { background-position: 0% 50%; }
  25% { background-position: 100% 50%; }
  50% { background-position: 100% 100%; }
  75% { background-position: 0% 100%; }
  100% { background-position: 0% 50%; }
}

2. Radial Pulse (расширяющийся круг)

.gradient-pulse {
  background: radial-gradient(
    circle at 30% 30%,
    rgba(99, 102, 241, 0.15),
    transparent 50%
  );
  animation: pulse 8s ease-in-out infinite;
}

@keyframes pulse {
  0%, 100% {
    transform: scale(1);
    opacity: 0.5;
  }
  50% {
    transform: scale(1.2);
    opacity: 0.8;
  }
}

3. Mesh Gradient (несколько источников)

.mesh-gradient {
  background:
    radial-gradient(ellipse at 20% 80%, rgba(99, 102, 241, 0.15), transparent 50%),
    radial-gradient(ellipse at 80% 20%, rgba(236, 72, 153, 0.15), transparent 50%),
    radial-gradient(ellipse at 50% 50%, rgba(139, 92, 246, 0.1), transparent 50%);
  background-size: 100% 100%;
  animation: mesh-move 20s ease-in-out infinite alternate;
}

@keyframes mesh-move {
  0% {
    background-position: 0% 0%, 100% 100%, 50% 50%;
  }
  100% {
    background-position: 100% 100%, 0% 0%, 60% 40%;
  }
}

4. Gradient Border (подвижная рамка)

.gradient-border {
  position: relative;
  border-radius: 20px;
  padding: 2px; /* border width */
  background: linear-gradient(90deg, #6366f1, #ec4899, #f43f5e, #6366f1);
  background-size: 300% 100%;
  animation: border-gradient 4s linear infinite;
}

.gradient-border::before {
  content: '';
  position: absolute;
  inset: 0;
  border-radius: 18px;
  background: #0a0a0a;
  z-index: -1;
}

@keyframes border-gradient {
  0% { background-position: 0% 50%; }
  100% { background-position: 100% 50%; }
}

Glassmorphism Card (Stripe style)

.glass-card {
  position: relative;
  background: rgba(255, 255, 255, 0.03);
  backdrop-filter: blur(20px);
  -webkit-backdrop-filter: blur(20px);
  border: 1px solid rgba(255, 255, 255, 0.08);
  border-radius: 20px;
  overflow: hidden;
}

.glass-card::before {
  content: '';
  position: absolute;
  inset: 0;
  background: linear-gradient(
    135deg,
    rgba(255, 255, 255, 0.05) 0%,
    transparent 50%
  );
  pointer-events: none;
}

Hero Gradient Background (Stripe.com style)

<section class="hero-gradient">
  <div class="gradient-orb orb-1"></div>
  <div class="gradient-orb orb-2"></div>
  <div class="gradient-orb orb-3"></div>
  <div class="hero-content">
    <h1>Your text here</h1>
  </div>
</section>

.hero-gradient {
  position: relative;
  min-height: 60vh;
  overflow: hidden;
  background: #0a0a0a;
}

.gradient-orb {
  position: absolute;
  border-radius: 50%;
  filter: blur(80px);
  opacity: 0.4;
  animation: orb-float 20s ease-in-out infinite;
}

.orb-1 {
  width: 600px;
  height: 600px;
  background: radial-gradient(circle, #6366f1, transparent 70%);
  top: -20%;
  left: -10%;
  animation-delay: 0s;
}

.orb-2 {
  width: 500px;
  height: 500px;
  background: radial-gradient(circle, #ec4899, transparent 70%);
  bottom: -20%;
  right: -5%;
  animation-delay: -5s;
}

.orb-3 {
  width: 400px;
  height: 400px;
  background: radial-gradient(circle, #10b981, transparent 70%);
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  animation-delay: -10s;
}

@keyframes orb-float {
  0%, 100% {
    transform: translate(0, 0) scale(1);
  }
  25% {
    transform: translate(50px, -30px) scale(1.1);
  }
  50% {
    transform: translate(-30px, 50px) scale(0.95);
  }
  75% {
    transform: translate(30px, 30px) scale(1.05);
  }
}

Animated Button Gradient

.btn-gradient-animated {
  position: relative;
  padding: 14px 28px;
  border: none;
  border-radius: 12px;
  font-weight: 600;
  color: white;
  cursor: pointer;
  overflow: hidden;
  transition: transform 0.3s ease, box-shadow 0.3s ease;
}

.btn-gradient-animated::before {
  content: '';
  position: absolute;
  inset: 0;
  background: linear-gradient(
    120deg,
    #6366f1,
    #8b5cf6,
    #ec4899,
    #f43f5e,
    #6366f1
  );
  background-size: 300% 100%;
  animation: btn-gradient 6s ease infinite;
}

.btn-gradient-animated:hover {
  transform: translateY(-2px);
  box-shadow: 0 8px 30px rgba(99, 102, 241, 0.3);
}

@keyframes btn-gradient {
  0% { background-position: 0% 50%; }
  50% { background-position: 100% 50%; }
  100% { background-position: 0% 50%; }
}

Anti-patterns

❌ Плохо	✅ Хорошо
`animation: 3s` — слишком быстро (мозг не успевает)	`animation: 15–30s` — медленное плавное движение
Яркие цвета `#ff0000`	Приглушённые `rgba(99,102,241,0.15)`
Без `filter: blur()` на орбах	`blur(80–120px)` для мягких переходов
Без `prefers-reduced-motion`	Уважать настройки пользователя
Градиент на тексте без fallback	Всегда `-webkit-background-clip`

Performance

/* ✅ Good — CSS animation (GPU accelerated) */
.gradient-bg {
  animation: gradient-shift 15s ease infinite;
  will-change: background-position;
}

/* ❌ Bad — JS animation (main thread) */
element.animate([
  { backgroundPosition: '0% 50%' },
  { backgroundPosition: '100% 50%' }
], { duration: 15000, iterations: Infinity });

CV Service Validation

# Проверить визуальную гармонию градиентов
curl -s -X POST http://localhost:8001/design/analyze \
  -H "Content-Type: application/json" \
  -d '{"image_base64": "...", "full_analysis": false}' | python3 -c "
import sys, json
d = json.load(sys.stdin)
color = d['dimensions'].get('color_harmony', {})
print(f\"Color Harmony: {color.get('score', 'N/A')}/10\")
print(f\"  Palette: {color.get('palette', 'N/A')}\")
"

Ожидается: color_harmony > 6.
