## How to use React Bootstrap Alert component
CoreUI’s React Bootstrap Alerts provide contextual feedback messages for typical user interactions. Each alert supports Bootstrap-based colors and can include additional content and dismiss functionality.
```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 display an alert (initially hidden), then dismiss it using the built-in close button — styled the Bootstrap way.
>
> ```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
>
> To include links inside your alert, use the `` component — it automatically adopts the contextual Bootstrap color of the parent alert.
>
> ```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 Bootstrap Alerts can include extra structured content such as headings, paragraphs, and horizontal rules for enhanced readability.
>
> ```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
>
> Use CoreUI Icons and flexbox utilities to add icons to your alerts. Combine them with spacing utilities for precise layout control.
>
> ```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 in your alert? CoreUI Icons can be stacked or arranged using flex utilities.
>
> ```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 style
>
> Add `variant="solid"` to give the alert a solid background color, in line with Bootstrap’s solid alert variants.
>
> ```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
>
> Use the `dismissible` prop to allow users to close the alert. This will completely remove it from the DOM.
>
> ```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.
