Certainly! Here are five relevant examples demonstrating various aspects of CSS animation:

### 1. Basic Transition:

```html

<!DOCTYPE html>

<head>

<style>

.box {

width: 100px;

height: 100px;

background-color: #3498db;

transition: background-color 0.5s ease-in-out;

}

.box:hover {

background-color: #e74c3c;

}

</style>

</head>

<body>

</body>

</html>

```

This example demonstrates a basic CSS transition. When you hover over the box, the background color smoothly transitions from blue to red.

### 2. Keyframe Animation:

```html

<!DOCTYPE html>

<head>

<style>

@keyframes rotate {

from { transform: rotate(0deg); }

to { transform: rotate(360deg); }

}

.spinner {

width: 50px;

height: 50px;

border: 5px solid #2ecc71;

border-top: 5px solid #3498db;

border-radius: 50%;

animation: rotate 2s linear infinite;

}

</style>

</head>

<body>

</body>

</html>

```

This example uses keyframes to create a rotating spinner. The `rotate` animation is applied to a circular div, creating a visually appealing spinning effect.

### 3. Animation Shorthand:

```html

<!DOCTYPE html>

<head>

<style>

.pulse {

width: 50px;

height: 50px;

background-color: #e67e22;

animation: pulse 1s ease-in-out infinite;

}

@keyframes pulse {

0% { transform: scale(1); }

50% { transform: scale(1.2); }

100% { transform: scale(1); }

}

</style>

</head>

<body>

</body>

</html>

```

Here, the `pulse` class uses the shorthand `animation` property to create a pulsating effect. The div scales up and down infinitely with a smooth easing function.

### 4. 3D Transformation:

```html

<!DOCTYPE html>

<head>

<style>

.cube {

width: 100px;

height: 100px;

background-color: #3498db;

transform: rotateX(45deg) rotateY(45deg);

animation: rotateCube 3s linear infinite;

}

@keyframes rotateCube {

0% { transform: rotateX(0deg) rotateY(0deg); }

100% { transform: rotateX(360deg) rotateY(360deg); }

}

</style>

</head>

<body>

</body>

</html>

```

This example showcases a 3D transformation using the `rotateX` and `rotateY` properties, creating a rotating cube effect.

### 5. Responsive Animation:

```html

<!DOCTYPE html>

<head>

<style>

.responsive-box {

width: 50px;

height: 50px;

background-color: #27ae60;

transition: transform 0.5s ease-in-out;

}

@media (max-width: 600px) {

.responsive-box:hover {

transform: scale(1.5);

}

</style>

</head>

<body>

</body>

</html>

```

This example demonstrates a responsive animation. On larger screens, the box changes color on hover, and on smaller screens (less than 600px), it scales up when hovered. The media query ensures a tailored animation for different screen sizes.
