jquery css animation javascript

I'm sure I'm missing something obvious here, but I am encountering an issue where using jQuery's `.fadeIn()` method on elements that have variable heights is causing layout shifts that disrupt the user experience. My setup involves jQuery version 3.6.0 and I am dynamically revealing sections of content based on user interactions. When I initially hide these sections using `.hide()`, their heights are not accounted for in the layout. Then, when I call `.fadeIn()`, the sudden appearance of these elements causes a noticeable jump in the content area because the surrounding elements do not adjust until layout recalculation is triggered. I've tried wrapping the `.fadeIn()` call inside a resize event and using CSS transitions for smoother rendering, but the issue persists. Here’s a simplified version of my code: ```javascript $(document).ready(function() { $('.toggle-button').click(function() { var $content = $(this).next('.content'); $content.fadeIn(300); }); }); ``` In my CSS, I'm using `display: none;` to initially hide the content sections. I have also experimented with setting the height of these sections to `auto` before calling `.fadeIn()`, but it doesn’t seem to help. The following CSS is applied: ```css .content { display: none; /* other styling */ } ``` I’ve read that using `.slideDown()` might alleviate some of the shifting because it animates height, but I need the fade effect for design consistency. Is there a recommended approach to handle this situation effectively while maintaining the fade-in effect? Any insights, especially regarding layout recalculation or a specific method to apply, would be greatly appreciated! This is part of a larger API I'm building. Has anyone else encountered this?
