### Last item with remaining available height
|
|
|
|
Take advantage of available viewport space by giving the last element the remaining available space in current viewport, even when resizing the window.
|
|
|
|
#### HTML
|
|
|
|
```html
|
|
<div class="container">
|
|
<div>Div 1</div>
|
|
<div>Div 2</div>
|
|
<div>Div 3</div>
|
|
</div>
|
|
```
|
|
|
|
#### CSS
|
|
|
|
```css
|
|
html,
|
|
body {
|
|
height: 100%;
|
|
margin: 0;
|
|
}
|
|
|
|
.container {
|
|
height: 100%;
|
|
display: flex;
|
|
flex-direction: column;
|
|
}
|
|
|
|
.container > div:last-child {
|
|
background-color: tomato;
|
|
flex: 1;
|
|
}
|
|
```
|
|
|
|
#### Demo
|
|
|
|
#### Explanation
|
|
|
|
1. `height: 100%` set the height of container as viewport height.
|
|
2. `display: flex` enables flexbox.
|
|
3. `flex-direction: column` set the direction of flex items' order from top to down.
|
|
4. `flex-grow: 1` the flexbox will apply remaining available space of container to last child element.
|
|
|
|
The parent must have a viewport height. `flex-grow: 1` could be applied to the first or second element, which will have all available space.
