animating height from `0` to `auto` in css can be challenging due to the nature of the `auto` value, which cannot be directly animated. however, there are effective techniques to achieve a similar effect using css transitions and javascript or css custom properties.

approach 1: using javascript

one common method involves using javascript to calculate the height of the element and then applying the height dynamically. here’s how you can do that:

step-by-step tutorial

1. **html structure**: create a simple html structure with a toggling button and a collapsible content section.

2. **css styles**: set up the initial styles for the collapsible content.

3. **javascript logic**: use javascript to toggle the height of the content from `0` to its natural height.

meta name="viewport" content="width=device-width, initial-scale=1.0"
link rel="stylesheet" href="styles.css"

div id="collapsiblecontent" class="collapsible"

/div

script src="script.js"/script
/body

}

collapsiblecontent {

transition: height 0.3s ease; /* transition for height */
}

.collapsible.active {
height: auto; /* set height to auto when active */
}
```

**javascript (script.js):**
```javascript
document.getelementbyid('togglebutton').addeventlistener('click', function() {
const content = document.getelementbyid('collapsiblecontent');

if (content.style.height) {
