css animations can create engaging and dynamic effects on web pages, enhancing user experience. however, animating elements that are set to `display: none` can be tricky because such elements are not part of the document flow and thus cannot be animated directly. instead, we typically use `opacity` and `visibility` to achieve similar effects.

objective
in this tutorial, we’ll create a smooth fade-out animation for an element that we want to hide, simulating the effect of animating `display: none`.

steps to animate an element on hide

1. **html structure**: create a simple html structure with an element that will be animated.
2. **css styling**: define the styles for the element and the animations.
3. **javascript interaction**: use javascript to trigger the animation and change the display property.

example code

html
```html
!doctype html
html lang="en"
head
meta charset="utf-8"
meta name="viewport" content="width=device-width, initial-scale=1.0"
titlecss fade out animation/title
link rel="stylesheet" href="styles.css"
/head
body
div class="box" id="box"hello, i will fade out!/div
button id="togglebutton"toggle fade/button
script src="script.js"/script
/body
/html
```

css (styles.css)
```css
body {
font-family: arial, sans-serif;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
height: 100vh;
background-color: f0f0f0;
}

.box {
width: 200px;
height: 100px;
background-color: 007bff;
color: white;
display: block;
opacity: 1;
visibility: visible;
transition: opacity 0.5s ease, visibility 0.5s ease;
}

.box.hidden {
opacity: 0;
visibility: hidden;
}
```

javascript (script.js)
```javascript
const box = document.getelementbyid('box');
const togglebutton = document.getelementbyid('togglebutton');

togglebutton.addeventlistener('click', () = {
box.classlist.toggle('hidden');
});
```
