Bootstrap Alert Colors

Overview

The alerts are created by these components you even usually do not think of until you truly get to require them. They are taken for giving prompt in time comments for the user interacting with the web-site hopefully aiming his or hers focus to a specific course or evoking special actions.

The alerts are most frequently used together with forms to give the user a idea if a field has been completed inaccurately, which is the appropriate format expected or which is the status of the submission once the submit button has been clicked.

As most of the elements in the Bootstrap framework the alerts also do have a neat predefined visual aspect and semantic classes which may possibly be used according to the particular situation where the Bootstrap Alert has been presented on display. Since it's an alert notification it is necessary to obtain user's focus but after all keep him in the zone of comfort nevertheless it might even be an error message. ( read here)

This gets achieved due to the use of mild pale colors each being intuitively attached to the semantic of the message content such as green for Success, Light Blue for basic information, Light yellow aiming for user's interest and Mild red indicating there is in fact something wrong.

Color of the url

It may not be noticed at a look but the font color itself is in fact following this color scheme too-- just the colors are much much darker so get unconsciously takened as black however it's not exactly so.

Exact same works not only for the alert text message in itself but as well for the links included in it-- there are link classes removing the outline and coloring the anchor elements in the appropriate colour so they suit the overall alert text appearance.

  <strong>Heads up!</strong> This <a href="#" class="alert-link">alert needs your attention</a>, but it's not super important.

<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>

Extra related information for alerts

A factor to consider-- the colors offer their obvious meaning just for those who actually get to see them. And so it's a good idea to as well ensure that the visible message itself brings the meaning of the alert well enough or to eventually include several extra explanations to only be seen by the screen readers if you want to provide the page's accessibility .

Besides links and simple HTML tags like strong for example the alert elements in Bootstrap 4 can also include Headings and paragraphs for the cases when you would like to display a bit longer content ( learn more).

<div class="alert alert-success" role="alert">
  <h4 class="alert-heading">Well done!</h4>
  <p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
  <p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
</div>

Reject the alert

Once more ensure the visual comfort of the visitors, you can also add an X icon to dismiss the alert and add a cool transition to it to.

Bootstrap alert dismissing
<div class="alert alert-warning alert-dismissible fade show" role="alert">
  <button type="button" class="close" data-dismiss="alert" aria-label="Close">
    <span aria-hidden="true">×</span>
  </button>
  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
</div>

There are four varieties of contextual alert messages in Bootstrap 4 framework - they are knowned as Success, Info, Warning and Danger. Do not let however their titles to limit the manner you're making use of them-- all of these are just a number of color schemes and the way they will be really implemented in your web site is completely up to you and totally depends on the special scenario.

For example-- if the color scheme of your page works with the red as basic colour it maybe very most suitable to display the alert for successful form submission in red as well working with the predefined alert danger appearance in order to better mix with the page and save some time defining your own classes.

Anyway the predefined alert classes are simply some consistent looks and the responsibility for working with them lays entirely on the designer's shoulders.
