Bootstrap Alerts
The bootstrap alert messages are commonly used to any important messages such as warning or confirmation messages to the end users.  Add dismiss functionality to all alert messages with this plugin.

When using a .close button, it must be the first child of the .alert-dismissible and no text content may come before it in the markup.
Usage
Just add data-dismiss="alert" to your close button to automatically give an alert close functionality. Closing an alert removes it from the DOM.

Bootstrap provides an easy way to add close functionality to the alert messages box. Just add the data-dismiss="alert" to the close button and it will automatically enable the dismissal of the containing alert message box.
