## Affix
|
|||
|
|
|
|||
|
|
Fix the element to a specific visible area.
|
|||
|
|
|
|||
|
|
### Basic usage
|
|||
|
|
|
|||
|
|
Affix is fixed at the top of the page by default.
|
|||
|
|
|
|||
|
|
:::demo You can set `offset` attribute to change the offset top，the default value is 0。
|
|||
|
|
```html
|
|||
|
|
<el-affix :offset="120">
|
|||
|
|
<el-button type="primary">Offset top 120px</el-button>
|
|||
|
|
</el-affix>
|
|||
|
|
```
|
|||
|
|

|
|||
|
|
|
|||
|
|
### Target container
|
|||
|
|
|
|||
|
|
You can set `target` attribute to keep the affix in the container at all times. It will be hidden if out of range.
|
|||
|
|
|
|||
|
|
:::demo Please notice that the container avoid having scrollbar.
|
|||
|
|
```html
|
|||
|
|
<div class="affix-container">
|
|||
|
|
<el-affix target=".affix-container" :offset="80">
|
|||
|
|
<el-button type="primary">Target container</el-button>
|
|||
|
|
</el-affix>
|
|||
|
|
</div>
|
|||
|
|
```

### Fixed position

|||
|

|
|||

|
The affix component provides two fixed positions: `top` and `bottom`.
|
|||
|
|
|
|||
|
|
:::demo You can set `position` attribute to change the fixed position, the default value is `top`.
|
|||
|
|
```html
|
|||
|
|
<el-affix position="bottom" :offset="20">
|
|||
|
|
<el-button type="primary">Offset bottom 20px</el-button>
