What are CSS3 transitions and how do I use them?

CSS3 transitions allow you to change property values smoothly over a specified duration. You can use them to enhance user experience by animating changes in CSS properties.

Can you give me an example of how to implement a CSS3 transition?

Sure! Here's a simple example:

.box {
  width: 100px;
  height: 100px;
  background-color: blue;
  transition: background-color 0.5s ease;
}

.box:hover {
  background-color: red;
}

This will change the box's background color from blue to red when hovered over.

What properties can I animate with CSS3 transitions?

You can animate various properties like color, background-color, width, height, opacity, transform, and more. Just ensure the property is animatable!

Are there any performance considerations I should keep in mind?

Yes, it's best to animate properties that are GPU-accelerated, like transform and opacity, to ensure smoother performance.
