If you are experiencing large black borders above and below your embedded video on Webflow, despite it being the desired size on YouTube, it is likely due to the aspect ratio mismatch between your video and the container it is embedded in. Here's what you can try to resolve this issue:
1. Check the aspect ratio: First, ensure that the aspect ratio of your container matches the aspect ratio of your video. Aspect ratio refers to the proportional relationship between the width and height of an element. For example, if your container is 16:9, your video should also have a 16:9 aspect ratio. If the aspect ratios do not match, black bars may appear to compensate for the difference.
2. Adjust the container size: If the aspect ratios match and you're still seeing black bars, the container size may need to be adjusted. In Webflow, you can modify the size of the container using CSS or the Webflow Designer. Make sure that the width and height of the container are set correctly to accommodate the aspect ratio of your video.
3. Use the Webflow video element: Instead of embedding the YouTube video directly, you can try using the Webflow video element. This element is specifically designed to handle video playback and can automatically adjust the aspect ratio to match your video content. Simply drag and drop the video element onto your Webflow page, and then paste the YouTube video URL into the video source field.
4. CSS adjustments: If the above solutions don't work, you can try applying custom CSS to the container or the video element itself. For example, you can use the CSS properties `object-fit` and `object-position` to control how the video is displayed within the container. Experiment with different values for these properties to find the right fit for your video.
Additionally, it's worth noting that YouTube provides different embedding methods (iframe, HTML5, etc.), and each method may have different behavior when it comes to responsiveness and aspect ratio. You may want to try different embedding methods to see if they yield better results.
Remember to preview your changes on different devices and screen sizes to ensure that the video displays properly and responsively across various devices.
