Alerts
Examples
Alerts are available for any length of
                                                text, as well as an optional dismiss button. For proper styling, use one
                                                of the four required contextual classes (e.g., .alert-success). For inline
                                                dismissal, use the alerts jQuery plugin.
Link color
Use the .alert-link utility class to
                                                quickly provide matching colored links within any alert.
