Video embedding isn't that tough at all. For this tutorial, I'm going to use a youtube video and embed it in my web page.
1) First, search for a video that you want embed in your web page. Click to view that video.
2) Look for a share button under the video (Most videos on the internet have a similar share button, if you're trying to embed your video from any other source than Youtube, look for a share button). Click that button, and you should see what is displayed in the image below.
3) And similarly, like most videos will have a share button, they should have an embed button like this one shown in the screenshot above. Click that embed button and move on to the next step.
4) After you click the embed button, you should be provided with a piece of code. In the screenshot above, you can see some iframe code in the right panel. Copy that code or click the copy button. Then move on to the next step.
