alert well enough or to eventually add some additional descriptions to only be seen by the screen readers in order to grant the page's accessibility.

In addition to links and simple HTML tags like strong as an example the alert elements in Bootstrap 4 can also include Headings and paragraphs for the situations when you want to display a bit longer web content.

  <p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
</div>

    <span aria-hidden="true">×</span>
  </button>

Don't allow however their names to decrease the manner in which you're working with them-- all of these are simply some color schemes and the way they will be really implemented in your web site is totally up to you and completely depends on the particular circumstance.

As an example-- if the colour scheme of your page makes use of the red as major colour it maybe pretty well-suited to present the alert for successful form submission in red as well using the predefined alert danger look in order to much better mix with the web page and save some time defining your own classes.
