They are taken for giving prompt in time responses for the user having interaction with the website hopefully pointing his or hers attention to a specific course or evoking special actions.
The alerts are most commonly used together with forms to give the user a tip if a area has been submitted improperly, which is the right format expected or which is the status of the submission after the submit button has been pressed.
As most of the elements in the Bootstrap framework the alerts also do have a well-kept predefined appearance and semantic classes that can be used according the particular circumstance where the Bootstrap Alert Colors has been displayed on display. As it's an alert notice it is very important to get user's interest but after all leave him in the zone of comfort nevertheless it might even be an error text message.
This gets accomplished by the use of gentle toned colours each being intuitively connected to the semantic of the message material such as green for Success, Light Blue for general info, Pale yellow desiring for user's focus and Mild red specifying there is really something wrong.
<div class="alert alert-success" role="alert"> <strong>Well done!</strong> You successfully read this important alert message. </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>

A detail to keep in mind-- the colours come with their obvious meaning only for those who in fact get to notice them. In this way it's a good idea to either be sure the noticeable text itself carries the meaning of the alert well enough or to eventually add certain additional descriptions to only be seen by screen readers in order to grant the page's accessibility .

As an example-- if the color design of your page utilizes the red as basic colour it maybe quite most suitable to present the alert for successful form submission in red too using the predefined alert danger appearance in order to better blend with the web page and save time defining your own classes.
Anyway the predefined alert classes are just some consistent looks and the responsibility for working with them lays entirely on the designer's shoulders.
