How do you make a youtube video stop at a certain time?

To make a YouTube video stop at a certain time, you can add a parameter to the video URL called "start" that specifies the time in seconds where you want the video to stop. Here's how you can do it in HTML: 1. Find the YouTube video you want to embed on the YouTube website. 2. Click on the "Share" button below the video player. 3. Click on the "Embed" button to get the embed code. 4. Copy the embed code and paste it into your HTML document where you want the YouTube video to appear. 5. In the YouTube embed code, locate the "src" attribute of the "iframe" element. 6. Add the parameter "&start=" followed by the time in seconds where you want the video to stop. For example, if you want the video to stop at 1 minute and 30 seconds, you would add "&start=90" to the end of the video URL. 7. Save and publish your HTML document with the updated YouTube embed code. 8. Now when someone plays the embedded YouTube video on your webpage, it will automatically stop at the specified time. Here's an example of how the updated YouTube embed code with the "start" parameter might look like: ``` ```
