^ there is the code. you need to replace the XXXXXXXX with the link from the youtube video. click share on the youtube video, than click embed, and copy only the url from the code and paste it where it says XXXXXXXX in the code. for example, here is the code for "baby one more time" by britney spears:
<iframe width="0" height="0" src="https://www.youtube.com/embed/C-u5WLJ9Yk4?si=41ZroCDNbJbOWM7N/?&;amp;;autoplay=1&;loop=1&;controls=1" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" loading="lazy"></iframe>
remember, only change the XXXXXXX in the code... the /?&; and other things you see in the code need to STAY for the code to work.
