What are the best practices for CSS transitions?

When using CSS transitions, it's important to keep them smooth and performant. Here are some best practices: 1. Limit the properties you animate. 2. Use transform and opacity for better performance. 3. Keep transitions short and sweet, ideally under 300ms. 4. Avoid animating layout properties like width and height.

Why should I use transform and opacity?

Using transform and opacity is recommended because they are handled by the GPU, which makes animations smoother and reduces the load on the CPU. This results in better performance, especially on mobile devices.

Can you give an example of a simple transition?

Sure! Here's a simple example:

.button {
  transition: background-color 0.3s ease;
}
.button:hover {
  background-color: blue;
}

This will smoothly change the button's background color when hovered.

What should I avoid when using transitions?

Avoid animating properties that trigger layout changes, like width, height, or margin. These can cause reflows and make animations choppy. Stick to transform and opacity for smoother effects.
