Alerts are messages to users when something is wrong. For example, if a user types in an incorrect email address or
credit card number, they’ll receive an error alert message, prompting them to make corrections.
.alert-primary
You can create colorful alerts for any texts. Primary alert (more important message) is in light blue color.
<div class=”alert alert-primary” role=”alert”>Primary alert</div>
.alert-secondary
Add a secondary alert (less important message) in light gray color.
<div class=”alert alert-secondary” role=”alert”>I’m a secondary alert</div>
.alert-success
This will alert a user that their action has been successful
<div class=”alert alert-success” role=”alert”>Success alert!</div>
.alert-warning
This will send a message of an upcoming action.
<div class=”alert alert-warning” role=”alert”>Warning! Warning!</div>

A danger alert is similar to a warning alert, but for more negative actions (e.g., getting locked out after too many password
fails)
<div class=”alert alert-danger” role=”alert”> You are in grave danger, my friend!</

</div>
