In today's fast-paced web world, user experience is key. Whether it’s a form validation or content loading, having a smooth loading indicator can significantly enhance user satisfaction. This guide addresses how to create a loading circle that appears with a smooth transition when a user clicks a button.

This code causes your loading circle to pop up abruptly, which is not visually appealing. So how can we transition it smoothly instead?

Solution: Using CSS Transitions and JavaScript Classes

To create a smooth loading effect, we can harness the power of CSS transitions. Here's a concise breakdown of how to implement this effectively:

Conclusion

Creating a smooth loading circle can significantly improve user satisfaction during waiting times. By using a combination of CSS transitions and JavaScript class manipulation, you can create a visually appealing loading indicator that enhances your web application's overall user experience.

Feel free to adapt this solution to your projects, and happy coding!
