Animation Patterns Reference
Use this reference when generating presentations. Match animations to the intended feeling.
Effect-to-Feeling Guide
| Feeling |
Animations |
Visual Cues |
| Dramatic / Cinematic |
Slow fade-ins (1-1.5s), large-scale transitions (0.9 to 1), parallax scrolling |
Dark backgrounds, spotlight effects, full-bleed images |
| Techy / Futuristic |
Neon glow (box-shadow), glitch/scramble text, grid reveals |
Particle systems (canvas), grid patterns, monospace accents, cyan/magenta/electric blue |
| Playful / Friendly |
Bouncy easing (spring physics), floating/bobbing |
Rounded corners, pastel/bright colors, hand-drawn elements |
| Professional / Corporate |
Subtle fast animations (200-300ms), clean slides |
Navy/slate/charcoal, precise spacing, data visualization focus |
| Calm / Minimal |
Very slow subtle motion, gentle fades |
High whitespace, muted palette, serif typography, generous padding |
| Editorial / Magazine |
Staggered text reveals, image-text interplay |
Strong type hierarchy, pull quotes, grid-breaking layouts, serif headlines + sans body |
Entrance Animations
/* Fade + Slide Up (most versatile) */
.reveal {
opacity: 0;
transform: translateY(30px);
transition: opacity 0.6s var(--ease-out-expo),
transform 0.6s var(--ease-out-expo);
}
.visible .reveal {
opacity: 1;
transform: translateY(0);
}
/* Scale In */
.reveal-scale {
opacity: 0;
transform: scale(0.9);
transition: opacity 0.6s, transform 0.6s var(--ease-out-expo);
}
.visible .reveal-scale {
opacity: 1;
transform: scale(1);
}
/* Slide from Left */
.reveal-left {
opacity: 0;
transform: translateX(-50px);
transition: opacity 0.6s, transform 0.6s var(--ease-out-expo);
}
.visible .reveal-left {
opacity: 1;
transform: translateX(0);
}
/* Blur In */
.reveal-blur {
opacity: 0;
filter: blur(10px);
transition: opacity 0.8s, filter 0.8s var(--ease-out-expo);
}
.visible .reveal-blur {
opacity: 1;
filter: blur(0);
}
Background Effects
/* Gradient Mesh — layered radial gradients for depth */
.gradient-bg {
background:
radial-gradient(ellipse at 20% 80%, rgba(120, 0, 255, 0.3) 0%, transparent 50%),
radial-gradient(ellipse at 80% 20%, rgba(0, 255, 200, 0.2) 0%, transparent 50%),
var(--bg-primary);
}
/* Noise Texture — inline SVG for grain */
.noise-bg {
background-image: url("data:image/svg+xml,..."); /* Inline SVG noise */
}
/* Grid Pattern — subtle structural lines */
.grid-bg {
background-image:
linear-gradient(rgba(255,255,255,0.03) 1px, transparent 1px),
linear-gradient(90deg, rgba(255,255,255,0.03) 1px, transparent 1px);
background-size: 50px 50px;
}
Interactive Effects
/* 3D Tilt on Hover — adds depth to cards/panels */
class TiltEffect {
constructor(element) {
this.element = element;
this.element.style.transformStyle = 'preserve-3d';
this.element.style.perspective = '1000px';
this.element.addEventListener('mousemove', (e) => {
const rect = this.element.getBoundingClientRect();
const x = (e.clientX - rect.left) / rect.width - 0.5;
const y = (e.clientY - rect.top) / rect.height - 0.5;
this.element.style.transform = `rotateY(${x * 10}deg) rotateX(${-y * 10}deg)`;
});
this.element.addEventListener('mouseleave', () => {
this.element.style.transform = 'rotateY(0) rotateX(0)';
});
}
}
Troubleshooting
| Problem |
Fix |
| Fonts not loading |
Check Fontshare/Google Fonts URL; ensure font names match in CSS |
| Animations not triggering |
Verify Intersection Observer is running; check .visible class is being added |
| Scroll snap not working |
Ensure scroll-snap-type: y mandatory on html; each slide needs scroll-snap-align: start |
| Mobile issues |
Disable heavy effects at 768px breakpoint; test touch events; reduce particle count |
| Performance issues |
Use will-change sparingly; prefer transform/opacity animations; throttle scroll handlers |
