What are CSS transitions?

What are CSS transitions and how do they work?

CSS transitions allow you to change property values smoothly over a specified duration. They enhance user experience by providing visual feedback.

Can you give me an example of how to implement 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 changes the button's background color from blue to green when hovered.

What properties can be transitioned?

You can transition most CSS properties, including color, background-color, width, height, opacity, and transform.

Are there any performance considerations I should be aware of?

Yes, it's best to avoid transitioning properties that trigger layout changes, like width and height, as they can be less performant. Instead, use transform and opacity for smoother animations.
