How Can I Dynamically Generate WebKit Keyframe Rotation Values Using JavaScript?

Dynamically Generating Webkit Keyframe Values Using JavaScript

You're trying to incorporate random numbers generated by JavaScript into the CSS keyframe animation rotate. This can't be done directly as CSS doesn't recognize JavaScript variables.

To achieve this, you need to dynamically create or modify CSS rules through JavaScript and insert them into the CSS Object Model. Here's the corrected syntax:

function setRotationTransform(element, startRotation, endRotation) {
  var rotationCSS = `@-webkit-keyframes rotate {
    0% {-webkit-transform: rotate(${startRotation}deg);}
    100% {-webkit-transform: rotate(${endRotation}deg);}
  }`;

  // Insert the generated CSS rules into the CSSOM
  var styleElement = document.createElement('style');
  styleElement.type = 'text/css';
  styleElement.innerHTML = rotationCSS;
  document.head.appendChild(styleElement);

  // Apply the generated keyframe animation to the element
  element.style.animation = 'rotate 5s infinite alternate ease-in-out';
}

To apply this method, you would need the following steps:

1. Create a random number generator in JavaScript.
2. Use the setRotationTransform() function to dynamically generate the CSS keyframe rules using the random numbers.
3. Insert the generated CSS rules into the CSSOM.
4. Apply the rotate animation to the target element using element.style.animation = 'rotate 5s infinite alternate ease-in-out';.

This approach allows you to dynamically update the keyframe values and apply them to your CSS elements, resulting in dynamic rotations based on the random numbers generated by JavaScript.
