Ensures that an element self-clears its children.
|
|
|
|
- Use the `:after` pseudo-element and apply `content: ''` to allow it to affect layout.
|
|
- Use `clear: both` to make the element clear past both left and right floats.
|
|
- For this technique to work properly, make sure 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).
|
|
- **Note:** This is only useful if you are using `float` to build layouts. Consider using a more modern approach, such as the flexbox or grid layout.

```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;
|
|
padding: 4px;
|
|
}
|
|
```
