# Alert Provides contextual feedback messages for typical user actions. ```twig Your changes were saved successfully. Review them now. ``` ## Installation ```shell php bin/console ux:install alert --kit bootstrap ``` ## Usage ```twig A simple primary alert - check it out! ``` ## Accessibility Do not rely on color alone to communicate the alert's meaning. Include clear visible text or additional context for assistive technologies. Dismissal removes the alert from the document. When appropriate, listen for Bootstrap's `closed.bs.alert` event and move focus to a logical destination. ## Examples ### Contextual variants Use one of Bootstrap's eight contextual colors to match the message's purpose. ```twig
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!
``` ### Link color Use `alert-link` for links that inherit a suitable color from their alert variant. ```twig
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 Alerts can contain headings, paragraphs, dividers, and other structured content. ```twig

Aww yeah, you successfully read this important alert message. This example text is long enough to show how spacing works with additional content.

Whenever you need to, use margin utilities to keep things nice and tidy.

 ``` ### Icons Combine alerts with flex utilities and accessible inline icons. ```twig
An example alert with an icon
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
