# Notification
Displays a global notification message at a corner of the page.
## Basic usage
:::demo Element Plus has registered the `$notify` method and it receives an object as its parameter. In the simplest case, you can set the `title` field and the` message` field for the title and body of the notification. By default, the notification automatically closes after 4500ms, but by setting `duration` you can control its duration. Specifically, if set to `0`, it will not close automatically. Note that `duration` receives a `Number` in milliseconds.

## With types
We provide four types: success, warning, info and error.
:::demo Element Plus provides four notification types: `success`, `warning`, `info` and `error`. They are set by the `type` field, and other values will be ignored. We also registered methods for these types that can be invoked directly like `open3` and `open4` without passing a `type` field.

:::
## Custom position
Notification can emerge from any corner you like.
:::demo The `position` attribute defines which corner Notification slides in. It can be `top-right`, `top-left`, `bottom-right` or `bottom-left`. Defaults to `top-right`.
notification/positioning
:::
## With offset
Customize Notification's offset from the edge of the screen.
:::demo Set the `offset` attribute to customize Notification's offset from the edge of the screen. Note that every Notification instance of the same moment should have the same offset.

:::
## Use HTML string
`message` supports HTML string.
:::demo Set `dangerouslyUseHTMLString` to true and `message` will be treated as an HTML string.
notification/raw-html
:::
:::warning
Although `message` property supports HTML strings, dynamically rendering arbitrary HTML on your website can be very dangerous because it can easily lead to [XSS attacks](https://en.wikipedia.org/wiki/Cross-site_scripting). So when `dangerouslyUseHTMLString` is on, please make sure the content of `message` is trusted, and **never** assign `message` to user-provided content.
:::
## Hide close button
It is possible to hide the close button
:::demo Set the `showClose` attribute to `false` so the notification cannot be closed by the user.
notification/no-close
:::
## Global method
Element Plus has added a global method `$notify` for `app.config.globalProperties`. So in a vue instance you can call `Notification` like what we did in this page.
## Local import
```javascript
import { ElNotification } from 'element-plus'
```
In this case you should call `ElNotification(options)`. We have also registered methods for different types, e.g. `ElNotification.success(options)`. You can call `ElNotification.closeAll()` to manually close all the instances.
