What are CSS transitions and how do I use them?

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

Can you give me an example of a CSS transition?

Sure! Here's a simple example:

.button {
  background-color: blue;
  transition: background-color 0.5s ease;
}
.button:hover {
  background-color: green;
}

This will change the button's background color from blue to green when hovered over.

What properties can I animate with CSS transitions?

You can animate many properties, including color, background-color, width, height, opacity, and transform, among others.

Are there any performance considerations I should be aware of?

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