This chapter will discuss about alerts and the classes Bootstrap provides for alerts. Alerts provide a way to style messages to the user. They provide contextual feedback messages for typical user actions.

You can add an optional close icon to alert. For inline dismissal use the Alerts jQuery plugin.

You can add a basic alert by creating a wrapper <div> and adding a class of .alert and one of the four contextual classes (e.g., .alert-success, .alert-info, .alert-warning, .alert-danger). The following example demonstrates this −

Live Demo 

<div class = "alert alert-success">Success! Well done its submitted.</div>
<div class = "alert alert-info">Info! take this info.</div>
<div class = "alert alert-warning">Warning ! Dont submit this.</div>
<div class = "alert alert-danger">Error ! Change few things.</div>

Dismissal Alerts

To build a dismissal alert −

  • Add a basic alert by creating a wrapper <div> and adding a class of .alert and one of the four contextual classes (e.g., .alert-success, .alert-info, .alert-warning, .alert-danger)

  • Also add optional .alert-dismissable to the above <div> class.

  • Add a close button.

The following example demonstrates this −

Live Demo 
<div class = "alert alert-success alert-dismissable">
   <button type = "button" class = "close" data-dismiss = "alert" aria-hidden = "true">
      &times;
   </button>
	
   Success! Well done its submitted.
</div>

<div class = "alert alert-info alert-dismissable">
   <button type = "button" class = "close" data-dismiss = "alert" aria-hidden = "true">
      &times;
   </button>
	
   Info! take this info.
</div>

<div class = "alert alert-warning alert-dismissable">
   <button type = "button" class = "close" data-dismiss = "alert" aria-hidden = "true">
      &times;
   </button>
	
   Warning ! Dont submit this.
</div>

<div class = "alert alert-danger alert-dismissable">
   <button type = "button" class = "close" data-dismiss = "alert" aria-hidden = "true">
      &times;
   </button>
	
   Error ! Change few things.
</div>
Be sure to use the <button> element with the data-dismiss = "alert" data attribute.

Links in Alerts

To get links in alerts −

  • Add a basic alert by creating a wrapper <div> and adding a class of .alert and one of the four contextual classes (e.g., .alert-success, .alert-info, .alert-warning, .alert-danger)

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

Live Demo 
<div class = "alert alert-success">
   <a href = "#" class = "alert-link">Success! Well done its submitted.</a>
</div>

<div class = "alert alert-info">
   <a href = "#" class = "alert-link">Info! take this info.</a>
</div>

<div class = "alert alert-warning">
   <a href = "#" class = "alert-link">Warning ! Dont submit this.</a>
</div>

<div class = "alert alert-danger">
   <a href = "#" class = "alert-link">Error ! Change few things.</a>
</div>
