# React Alert Component
> React alert component gives contextual feedback information for common user operations. The alert component is delivered with a bunch of usable and adjustable alert messages.
## How to use React Alert Component.
React Alert is prepared for any length of text, as well as an optional close button. For a styling, use one of the **required** contextual `color` props (e.g., `primary`). For inline dismissal, use the [dismissing prop](#dismissing).
```html
import React from 'react'
import { CAlert } from '@coreui/react'
export const AlertExample = () => {
return (
<>
A simple primary alert—check it out!A simple secondary alert—check it out!A simple success alert—check it out!A simple danger alert—check it out!A simple warning alert—check it out!A simple info alert—check it out!A simple light alert—check it out!A simple dark alert—check it out!
)
}
```
> ### Live example
>
> Click the button below to show an alert (hidden with inline styles to start), then dismiss (and destroy) it with the built-in close button.
>
> ```html
import React, { useState } from 'react'
import { CAlert, CButton } from '@coreui/react'
export const AlertLiveExample = () => {
const [visible, setVisible] = useState(false)
return (
<>
setVisible(false)}>
A simple primary alert—check it out!
setVisible(true)}>
Show live alert
)
}
```
>
> ### Link color
>
> Use the `` component to immediately give matching colored links inside any react alert component.
>
> ```html
import React from 'react'
import { CAlert, CAlertLink } from '@coreui/react'
export const AlertLinkColorExample = () => {
return (
<>
A simple primary alert with an example link. Give it a
click if you like.
A simple secondary alert with an example link. Give it a
click if you like.
A simple success alert with an example link. Give it a
click if you like.
A simple danger alert with an example link. Give it a
click if you like.
A simple warning alert with an example link. Give it a
click if you like.
A simple info alert with an example link. Give it a click
if you like.
A simple light alert with an example link. Give it a click
if you like.
A simple dark alert with an example link. Give it a click
if you like.
)
}
```

> ### Additional content
>
> React Alert can also incorporate supplementary components & elements like heading, paragraph, and divider.
>
> ```html
import React from 'react'
import { CAlert, CAlertHeading } from '@coreui/react'
export const AlertAdditionalContentExample = () => {
return (
Well done!
Aww yeah, you successfully read this important alert message. This example text is going to
run a bit longer so that you can see how spacing within an alert works with this kind of
content.
Whenever you need to, be sure to use margin utilities to keep things nice and tidy.
)
}
```
>
> ### Icons
>
> Similarly, you can use [flexbox utilities](https://coreui.io/bootstrap/docs/utilities/flex) and [CoreUI Icons](https://coreui.io/icons/) to create react alerts with icons. Depending on your icons and content, you may want to add more utilities or custom styles.
>
> ```html
import React from 'react'
import { CAlert } from '@coreui/react'
export const AlertIcons1Example = () => {
return (
An example alert with an icon
)
}
```
>
> Need more than one icon for your react alerts? Consider using [CoreUI Icons](https://coreui.io/icons/).
>
> ```html
import React from 'react'
import { CAlert } from '@coreui/react'
import CIcon from '@coreui/icons-react'
import { cilBurn, cilCheckCircle, cilInfo, cilWarning } from '@coreui/icons'
export const AlertIcons2Example = () => {
return (
<>
An example alert with an icon
An example success alert with an icon
An example warning alert with an icon
An example danger alert with an icon
)
}
```
>
> ### Solid
>
> Use `variant="solid"` to change contextual colors to solid.
>
> ```html
import React from 'react'
import { CAlert } from '@coreui/react'
export const AlertSolidExample = () => {
return (
<>
A simple solid primary alert—check it out!
A simple solid secondary alert—check it out!
A simple solid success alert—check it out!
A simple solid danger alert—check it out!
A simple solid warning alert—check it out!
A simple solid info alert—check it out!
A simple solid light alert—check it out!
A simple solid dark alert—check it out!
)
}
```
>
> ### Dismissing
>
> React Alert component can also be easily dismissed. Just add the `dismissible` prop.
>
> ```html
import React from 'react'
import { CAlert } from '@coreui/react'
export const AlertDismissingExample = () => {
return (
{
alert('👋 Well, hi there! Thanks for dismissing me.')
}}
>
Go right ahead and click that dimiss over there on the right.
)
}
```
>
>
> When an alert is dismissed, the element is completely removed from the page structure. If a
> keyboard user dismisses the alert using the close button, their focus will suddenly be lost and,
> depending on the browser, reset to the start of the page/document.
