Sure, you can create a spinning wheel animation using CSS animations and JavaScript to control the rotation. Here's a simple example:
HTML:
```html
<div id="wheel" class="wheel">
<div id="pointer"></div>
<div class="segment">Value 1</div>
<div class="segment">Value 2</div>
<div class="segment">Value 3</div>
<div class="segment">Value 4</div>
</div>
<button onclick="spinWheel()">Spin</button>
<div id="result"></div>
```
CSS:
```css
.wheel {
width: 300px;
height: 300px;
position: relative;
border-radius: 50%;
border: 5px solid black;
}
.segment {
position: absolute;
width: 100%;
height: 100%;
transform-origin: 50% 100%;
border-bottom: 5px solid black;
text-align: center;
}
.segment:nth-child(1) { transform: rotate(0deg); }
.segment:nth-child(2) { transform: rotate(90deg); }
.segment:nth-child(3) { transform: rotate(180deg); }
.segment:nth-child(4) { transform: rotate(270deg); }
#pointer {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%) rotate(0deg);
width: 20px;
height: 20px;
background-color: red;
border-radius: 50%;
}
@keyframes rotateWheel {
0% { transform: rotate(0deg); }
100% { transform: rotate(1440deg); } /* 4 full rotations */
}
```
JavaScript:
```javascript
function spinWheel() {
var wheel = document.getElementById("wheel");
var resultElement = document.getElementById("result");
// Disable button during animation
var spinButton = document.querySelector("button");
spinButton.disabled = true;
// Randomly select a segment
var segments = document.getElementsByClassName("segment");
var segmentCount = segments.length;
var randomIndex = Math.floor(Math.random() * segmentCount);
var selectedSegment = segments[randomIndex];
// Calculate rotation angle
var rotationAngle = (randomIndex * 90) + (Math.random() * 90); // Randomize within segment
// Set animation properties
wheel.style.animation = "rotateWheel 5s cubic-bezier(0.68, -0.55, 0.27, 1.55) forwards";
selectedSegment.style.borderBottom = "5px solid red";
// Update result after animation ends
wheel.addEventListener("animationend", function() {
resultElement.textContent = selectedSegment.textContent;
wheel.style.animation = ""; // Reset animation
selectedSegment.style.borderBottom = "5px solid black"; // Reset segment style
spinButton.disabled = false; // Enable button
});
}
```
This code creates a spinning wheel with four segments. When you click the "Spin" button, it randomly selects one of the segments and spins the wheel accordingly. After spinning, it displays the selected value.
