Ensures that an element self-clears its children.
|
|
|
|
```html
|
|
<div class="clearfix">
|
|
<div class="floated">float a</div>
|
|
<div class="floated">float b</div>
|
|
<div class="floated">float c</div>
|
|
</div>
|
|
```
|
|
|
|
```css
|
|
.clearfix:after {
|
|
content: '';
|
|
display: block;
|
|
clear: both;
|
|
}
|
|
|
|
.floated {
|
|
float: left;
|
|
}
|
|
```
|

#### Explanation
|
|
|
|
- `.clearfix:after` defines a pseudo-element.
|
|
- `content: ''` allows the pseudo-element to affect layout.
|
|
- `clear: both` indicates that the left, right or both sides of the element cannot be adjacent to earlier floated elements within the same block formatting context.
|
|
- This is only useful if you are still using `float` to build layouts. Please consider using a modern approach with flexbox layout or grid layout. For this snippet to work properly you need to ensure that there are no non-floating children in the container and that there are no tall floats before the clearfixed container but in the same formatting context (e.g. floated columns).
