Alerts
Alerts are available for any length of text, as well as an optional close button. For proper styling, use one of the eight required contextual classes (e.g., .alert-success).
<div class="alert alert-primary" role="alert">
A simple primary alert—check it out!
</div>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.
Link color
Use the .alert-link utility class to quickly provide matching colored links within any alert.
Additional content
Alerts can also contain additional HTML elements like headings, paragraphs and dividers.
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 and Bootstrap Icons to create alerts with icons. Depending on your icons and content, you may want to add more utilities or custom styles.
