Hey there!

Good work so far!

  1. To use YouTube videos, you have to use a specific approach. You have to go to the specific YT video, click the Share button, click the </> button and copy and paste the code you see there into your code. The code starts with <iframe ...>

  2. So your media queries look like this:

@media (max-width: 100px);
  @media (min-height: 350px);

What do you expect it to do?

i use media query  as mention in requirments ,
