HTML5 Video Element Not Responsive in Bootstrap 5 - Aspect Ratio Issues on Resize

I'm collaborating on a project where I've been struggling with this for a few days now and could really use some help... I'm relatively new to this, so bear with me... I'm having trouble with the HTML5 `<video>` element not maintaining its aspect ratio when used within a Bootstrap 5 grid layout. I want to ensure that the video scales properly on window resize while keeping its original aspect ratio. I've set up my video like this: ```html <div class="container"> <div class="row"> <div class="col-md-6"> <video controls class="w-100"> <source src="video.mp4" type="video/mp4"> Your browser does not support the video tag. </video> </div> </div> </div> ``` The scenario arises when I resize the browser window; the video expands to fill the width but does not maintain its height proportionally, leading to distortion. I've tried adding the class `ratio ratio-16x9` from Bootstrap 5, but that doesn't seem to work as intended: ```html <div class="ratio ratio-16x9"> <video controls class="w-100"> <source src="video.mp4" type="video/mp4"> Your browser does not support the video tag. </video> </div> ``` However, the video doesn't stretch correctly in the parent container, and I receive a warning in the console about the video element not respecting the aspect ratio. I've also checked that my Bootstrap and CSS versions are compatible but still no luck. Is there a specific way to make the `<video>` element responsive while maintaining the aspect ratio that I've overlooked? Any tips or best practices would be appreciated! I'm working on a application that needs to handle this. How would you solve this? This is my first time working with Html 3.11. What are your experiences with this? I'm working with Html in a Docker container on Ubuntu 20.04. What would be the recommended way to handle this? How would you solve this?
