Examples

Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.

Wrap any text and an optional dismiss button in .alert and one of the four contextual classes (e.g., .alert-success) for basic alert messages.

No default class

Alerts don’t have default classes, only base and modifier classes. A default gray alert doesn’t make too much sense, so you’re required to specify a type via contextual class. Choose from success, info, warning, or danger.

<div class="alert alert-success" role="alert">
    <strong>Muito bom!</strong> Alerta usado para mensagens de sucesso.
  </div>
  <div class="alert alert-info" role="alert">
    <strong>Heads up!</strong> This alert needs your attention, but it's not super important.
  </div>
  <div class="alert alert-warning" role="alert">
    <strong>Warning!</strong> Better check yourself, you're not looking too good.
  </div>
  <div class="alert alert-danger" role="alert">
    <strong>Oh snap!</strong> Change a few things up and try submitting again.
  </div>

Dismissible alerts

Build on any alert by adding an optional .alert-dismissible and close button.

Requires JavaScript alert plugin

For fully functioning, dismissible alerts, you must use the alerts JavaScript plugin.

<div class="alert alert-warning alert-dismissible" role="alert">
  <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <strong>Warning!</strong> Better check yourself, you're not looking too good.
</div>

Ensure proper behavior across all devices

Be sure to use the <button> element with the data-dismiss="alert" data attribute.

Use the .alert-link utility class to quickly provide matching colored links within any alert.

<div class="alert alert-success" role="alert">
  <strong>Well done!</strong> You successfully read <a href="#" class="alert-link">this important alert message</a>.
</div>
<div class="alert alert-info" role="alert">
  <strong>Heads up!</strong> This <a href="#" class="alert-link">alert needs your attention</a>, but it's not super important.
</div>
<div class="alert alert-warning" role="alert">
  <strong>Warning!</strong> Better check yourself, you're <a href="#" class="alert-link">not looking too good</a>.
</div>
<div class="alert alert-danger" role="alert">
  <strong>Oh snap!</strong> <a href="#" class="alert-link">Change a few things up</a> and try submitting again.
</div>
