To embed a video in a Joomla article, follow these steps:
For example, to embed a YouTube video, you can use the following code:
<iframe width="560" height="315" src="https://www.youtube.com/embed/VIDEO_ID" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
Replace "VIDEO_ID" with the unique identifier of the video you want to embed.
Alternatively, you can use a Joomla extension to embed videos in your articles. Some popular options include AllVideos Reloaded and JoomlaWorks Simple Image Gallery. These extensions allow you to easily insert videos into your articles using a simple button or tag, without having to manually add the embed code.
