To add a functional button when programming an app, you first need to create the button element in your app's user interface. Then, you need to write the code that specifies what action should be performed when the button is clicked. This typically involves adding an event listener to the button element that triggers a specific function or piece of code. Finally, you need to test the button to ensure that it performs the desired action when clicked. **

This will hide the button from view while still allowing it to be interacted with. You can then use JavaScript to add event listeners or trigger the button's functionality programmatically. Additionally, you can also set the 'visibility' property to 'hidden' if you want the button to still take up space on the page but be invisible. **

Ultimately, it is a personal preference and can also depend on the occasion and the overall outfit. **
