jquery css dom-manipulation JavaScript

I'm reviewing some code and I'm working through a tutorial and I've been banging my head against this for hours... I just started working with I've searched everywhere and can't find a clear answer. I'm working with an scenario where I'm trying to change the CSS of newly added nested elements using jQuery's `.css()` method after appending them to the DOM. Specifically, I have a container where I'm appending div elements dynamically. However, when I try to set their background color immediately after appending them, it doesn't reflect on the page. Here's a simplified version of my code: ```javascript for (let i = 0; i < 3; i++) { const newDiv = $('<div class="child">Child ' + (i + 1) + '</div>'); $('#container').append(newDiv); newDiv.css('background-color', 'lightblue'); } ``` When I run this, the background color of these child divs is not set as expected. Instead, they appear without any background color. I checked the console, and there are no errors being thrown. To troubleshoot, I tried wrapping the `.css()` method call in a `setTimeout()` to see if a timing scenario was causing the question: ```javascript setTimeout(() => { newDiv.css('background-color', 'lightblue'); }, 0); ``` However, this didn't help either. It seems like the CSS rule is being overridden or not applied correctly after the append operation. I've also checked that the CSS is not being influenced by any other styles in my stylesheet, but I need to find the root cause. I'm using jQuery 3.6.0 and running this in Chrome 93. Any insights on what could be causing this behavior or how to ensure the CSS applies correctly after appending? Is there a better approach? For reference, this is a production desktop app. What am I doing wrong? I'm working with Javascript in a Docker container on Windows 10. How would you solve this? I'm working on a desktop app that needs to handle this. I'm working in a Windows 11 environment. Any help would be greatly appreciated!
