Default Alert
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).
Dismissing Alerts
Add a dismiss button and the .alert-dismissible class, which adds
extra padding to the right of the alert
and positions the .btn-close button.
Custom Alerts
Display alert with transparent background and with contextual text color. Use
classes
.bg-transparent, and .text-*. E.g. bg-transparent
text-primary.
Link Color
Use the .alert-link utility class to quickly provide matching
colored links within any alert.
Icons with Alerts
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.
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.
