I’m trying to make a YouTube video embedded in an iframe fully responsive, so it fills the entire width of its container, regardless of the screen size. I’ve been playing around with different CSS techniques but haven’t found the perfect solution yet.

To give you a little background, I want to ensure that the video maintains its aspect ratio while scaling down or up depending on the device—whether it’s a phone, tablet, or a desktop. Most importantly, I want the video to look good and not be distorted or have weird black bars around it.

I tried using a simple percentage for the width, but it didn’t seem to do the trick. I’ve heard about using CSS properties like “overflow” and “position,” but I’m not entirely sure how to implement them correctly for an iframe. Also, there are different ways to achieve responsiveness with CSS frameworks like Bootstrap, but I want to stick with pure CSS for now.

So, I was thinking maybe I could wrap the iframe in a div and then apply some clever CSS to that. But what’s the best way to handle the aspect ratio? I’ve seen some tutorials mention using something called “padding-bottom” to maintain the 16:9 aspect ratio, but I’m not quite clear on how that works. If anyone has had success with this or can share a code snippet or two, I’d really appreciate it.

What are the specific properties I should be focusing on? Should I set the iframe height to auto or use specific pixel values to achieve the best result? Also, if you have any tips on compatibility issues across different browsers or devices, that would be super helpful, too!

I know there are a lot of web-savvy people out there who’ve tackled this before, so I’m eager to hear your thoughts. How do you make your embedded YouTube videos fully responsive and maintain that nice aspect ratio?Thanks for any advice!
