This functionality is both user-friendly and aesthetically pleasing, making your application more interactive. What is BMI? BMI, or Body Mass Index, is a simple calculation used to assess whether a person is underweight, normal weight, overweight, or obese. It's calculated using the height and weight of a person. Implementing a BMI calculator in your application can be a handy tool for users to monitor their health. The Problem You might be wondering how to create a button that toggles the visibility of your BMI calculator. This is indeed a common challenge for developers. In our example, we will leverage HTML, CSS, and JavaScript to achieve this functionality. Solution Overview The solution involves creating a button that, when clicked, will toggle a class that hides or shows the corresponding element. We'll break our solution down into three key components: HTML structure, JavaScript functionality, and CSS styles.

The calculator itself remains intact, so users will still be able to interact with it without any loss of functionality. Final Thoughts Creating interactive elements such as a toggle visibility for a BMI calculator can enhance user experience significantly. By following these steps, you can improve your web applications and engage users more effectively. Happy coding, and enjoy building your projects!
