Question

There is a code snippet posted below so you can see.

After the X button fades in, click that.

X button fades in after the curtain goes up.

I was told this:

In your showContainer function, you are trying to add the slide class
to the container element when the animation of the spinner ends.
However, the slide class is supposed to transition the container
upwards, but it seems it’s not being applied correctly.

It should work the same way as:

How this one works:

window.onload = function() {
  const container = document.querySelector(".video-containerA");
  const spinner = document.querySelector(".spinner");
  const exitButton = document.querySelector(".exitA");

  spinner.addEventListener("animationend", function() {
    container.classList.add("slide");
  });

  container.addEventListener("transitionend", function() {
    exitButton.classList.add("visible");
  });
};

After clicking the exit button the curtain should go up.

After it is up, exit button should be visible

**How do I fix this?

I am confused here.

The curtain is not going up.

I don’t understand, it should be working.
