jquery fadeIn css DOM javascript

I'm writing unit tests and Hey everyone, I'm running into an issue that's driving me crazy....... I am trying to use jQuery's `.fadeIn()` method to reveal a specific element within a parent container that is initially hidden. However, the element does not fade in as expected when I call the function. The scenario arises when the parent container is hidden with CSS (`display: none;`) and then made visible with jQuery. Here's the code I am using: ```javascript $(document).ready(function() { $('#showButton').on('click', function() { $('#parentContainer').show(); // Making the parent container visible $('#childElement').fadeIn(); // Attempting to fade in the child element }); }); ``` Initially, the `#parentContainer` is set to `display: none;` in my CSS: ```css #parentContainer { display: none; } ``` When I click the button, the parent container shows up, but the child element `#childElement` doesn't fade in; it just appears instantly instead. I have tried adding a slight delay before the fade-in call like this: ```javascript $(document).ready(function() { $('#showButton').on('click', function() { $('#parentContainer').show(); setTimeout(function() { $('#childElement').fadeIn(); }, 100); }); }); ``` However, it still doesn't work as intended. I'm running jQuery version 3.6.0, and I am testing this in Chrome. Does anyone know why `.fadeIn()` is not working properly, and how I can achieve the desired fading effect for the child element after the parent container becomes visible? For context: I'm using Javascript on Debian. Any suggestions would be helpful. I'm working in a macOS environment. Cheers for any assistance! The project is a mobile app built with Javascript. How would you solve this?
