Why Doesn\'t My Slide Animation Work When Trying to Create a Fade Out Effect in CSS?

CSS3 Transition: Fade Out Effect

When attempting to implement a fade out effect using pure CSS, it may be confusing why a slide animation would not work. Here's why:

The key to a fade out effect lies in transitioning the opacity property. The top property, which is used for slide animations, will not produce the desired effect.

Fade Out Effect using CSS3 Transition

Here's an example of how to achieve a fade out effect using CSS3 transitions:

<code class="css">.hidden {
  visibility: hidden;
  opacity: 0;
  transition: opacity 2s linear;
}</code>

When this class is applied to an element, it will gradually fade out over a duration of 2 seconds.

Understanding the Differences:

The key difference between a fade out and slide animation lies in the property being transitioned. For a fade out effect, it's the opacity property, while for a slide animation, it's typically a position property like top or left.

In the case of the provided code, the animation is set to transform the top property, which will move the element off the screen rather than fading it out.
