CSS Multiple Animations: Complete Guide with Practical Examples

CSS animations help bring modern websites to life. From subtle UI effects to advanced motion designs, animations improve user experience when used correctly. One powerful feature many developers overlook is CSS multiple animations, which allows you to apply more than one animation to a single element—without using JavaScript.

In this guide, you’ll learn how CSS multiple animations work, how to use them correctly, and common mistakes to avoid.

What Are CSS Multiple Animations?

CSS multiple animations allow you to run two or more animations at the same time or with different timings on the same element. This is achieved by separating animation values with commas.

According to MDN Web Docs, CSS animations are handled efficiently by the browser, making them a performance-friendly choice compared to script-based animations.

CSS Multiple Animations Syntax

You can define multiple animations using the shorthand animation property.

.element {
  animation: fadeIn 1s ease,
             slideUp 1s ease;
}

.element {
  animation: fadeIn 1s ease,
             slideUp 1s ease;
}

Each comma-separated group represents a separate animation applied to the same element.

Example 1: Fade In + Slide Up Animation

This animation is commonly used for cards, alerts, and content sections.

HTML

<div class="box">Welcome to Makemychance</div>

<div class="box">Welcome to Makemychance</div>

CSS

.box {
  padding: 20px;
  background: #21b039;
  color: #fff;
  animation: fadeIn 1s ease, slideUp 1s ease;
}

@keyframes fadeIn {
  from { opacity: 0; }
  to { opacity: 1; }
}

@keyframes slideUp {
  from { transform: translateY(30px); }
  to { transform: translateY(0); }
}

.box {
  padding: 20px;
  background: #21b039;
  color: #fff;
  animation: fadeIn 1s ease, slideUp 1s ease;
}

@keyframes fadeIn {
  from { opacity: 0; }
  to { opacity: 1; }
}

@keyframes slideUp {
  from { transform: translateY(30px); }
  to { transform: translateY(0); }
}

✔ The element fades in while moving upward smoothly.

Example 2: Rotation and Pulse Animation

This pattern is widely used in loaders and icons.

.icon {
  animation: rotate 4s linear infinite,
             pulse 1.5s ease-in-out infinite;
}

@keyframes rotate {
  to { transform: rotate(360deg); }
}

@keyframes pulse {
  0%, 100% { opacity: 1; }
  50% { opacity: 0.5; }
}

.icon {
  animation: rotate 4s linear infinite,
             pulse 1.5s ease-in-out infinite;
}

@keyframes rotate {
  to { transform: rotate(360deg); }
}

@keyframes pulse {
  0%, 100% { opacity: 1; }
  50% { opacity: 0.5; }
}

Controlling Duration and Delay

Each animation can have its own duration and delay.

.card {
  animation: fadeIn 0.5s ease,
             bounce 1s ease 0.6s;
}

.card {
  animation: fadeIn 0.5s ease,
             bounce 1s ease 0.6s;
}

This allows you to create layered and staggered animation effects without additional code.

Common Mistake: Transform Conflicts

A common issue with multiple animations is using transform in more than one animation.

❌ Problem:

@keyframes move {
  to { transform: translateX(40px); }
}

@keyframes rotate {
  to { transform: rotate(360deg); }
}

@keyframes move {
  to { transform: translateX(40px); }
}

@keyframes rotate {
  to { transform: rotate(360deg); }
}

Only one transform will apply.

✔ Solution:

• Combine transforms into one animation
• Or manage transforms carefully using a single keyframe

Performance Best Practices

To keep animations smooth and SEO-friendly:

• Animate only transform and opacity
• Avoid layout-changing properties like top or width
• Keep animations short and meaningful
• Use prefers-reduced-motion for accessibility

@media (prefers-reduced-motion: reduce) {
  * {
    animation: none !important;
  }
}

@media (prefers-reduced-motion: reduce) {
  * {
    animation: none !important;
  }
}

When Should You Use CSS Multiple Animations?

Use multiple animations when:

• Designing modern UI components
• Creating loaders, banners, and cards
• Improving UX without JavaScript
• Building performance-focused websites

Avoid excessive animations, as they can negatively affect user experience and Core Web Vitals.

Final Thoughts

CSS multiple animations allow you to create advanced motion effects while keeping your code clean and performant. By understanding how comma-separated animation values work, you can build smooth, professional UI interactions without relying on JavaScript.

For front-end developers, this is a practical skill that adds real value to modern web projects.
