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. Use transform and opacity for smoother animations.
2. Limit the number of properties being transitioned.
3. Use the 'ease' timing function for a natural feel.
4. Avoid transitions on large elements to maintain performance.

Can you explain why using transform and opacity is better?

Yes! Using transform and opacity is better because they are handled by the GPU, which allows for smoother animations without causing layout recalculations. This results in better performance.

What timing functions should I use for different effects?

For different effects, you can use:

• 'ease-in' for a slow start.
• 'ease-out' for a slow end.
• 'ease-in-out' for a smooth start and end.
• 'linear' for a constant speed throughout.

How can I optimize transitions for mobile devices?

To optimize transitions for mobile devices, consider the following:

1. Reduce the number of transitions to save processing power.
2. Use simpler animations that require less computation.
3. Test on actual devices to ensure performance is smooth.

Are there any common pitfalls to avoid?

Yes, common pitfalls include:

1. Overusing transitions, which can overwhelm users.
2. Transitioning properties that trigger layout changes, causing jank.
3. Not testing on multiple devices and browsers.
