In the keyframes part, my PC doesn't recognize the from part. If it would, it would be blue and the opacity command would be grey. But as you see none of them is correct and I don't know why. Because of this little error, my HTML website is not working the way it should. Can anyone please help me? I would like to finish my HTML website.

I'm not sure I fully understand your question, it might be helpful to reframe it, with a minimal reproducible example. See StackOverflows MRE

I don't see you calling the animation anywhere in your code. You need to target the nav links, and tell it to use the animation navLinkFade.

Here is an example of a super simple animation.

ul {
  animation: fade 3s forwards;
}


@keyframes fade {
  from {
    opacity: 0;
    transform: translateX(50px);
  }
  to {
    opacity: 1;
    transform: translateX(0px);
  }
}

<ul>
  <li>Test</li>
  <li>Test</li>
</ul>

I checked your code on my system. I can see both animation is working like expected.

Can you check with another browser? if you are still facing issue then explain more about issue?
