CSS3 Spin Animation Not Working: Why Are My Keyframes Missing?

CSS3 Spin Animation: Why It's Not Working

You've encountered an issue where CSS3 spin animation isn't functioning in your code. Before troubleshooting, it's crucial to understand the basic principle behind CSS3 animations.

Using CSS3 Animation Keyframes

To harness the power of CSS3 Animation, defining the animation keyframes is essential. Keyframes specify how an animated element should appear at different time intervals throughout the animation. In your code, you've referenced the animation named "spin," but these keyframes haven't been defined.

Refer to the official Mozilla developer guide (https://developer.mozilla.org/en-US/docs/CSS/Tutorials/Using_CSS_animations) for detailed information on CSS animation keyframes.

Implementation

Here's a snippet with keyframes added to demonstrate how spin animation can be implemented effectively:

HTML:

<code class="html"><div></div></code>

CSS:

<code class="css">div {
  margin: 20px;
  width: 100px;
  height: 100px;
  background: #f00;
  animation-name: spin;
  animation-duration: 4000ms;
  animation-iteration-count: infinite;
  animation-timing-function: linear;
}
@keyframes spin {
  from {
    transform: rotate(0deg);
  }
  to {
    transform: rotate(360deg);
  }
}</code>

In this code, we're defining the "spin" animation keyframes using the "from" and "to" selectors. These specify that the element will start at a 0-degree rotation and gradually rotate to 360 degrees over the animation duration.

By incorporating this keyframe definition, you'll enable the spin animation to function as intended in your code.
