Same goes not only for the alert message itself but even for the web links included in it-- there are link classes taking off the outline and colouring the anchor elements in the proper color so they match the overall alert text look.

More details for alerts

A factor to bear in mind-- the colours offer their clear interpretation only for those who actually get to notice them. So it's a good thing to either be sure the noticeable content itself offers the meaning of the alert well enough or to eventually bring in some extra information to only be seen by screen readers in order to grant the page's accessibility .

Along with links and simple HTML tags like strong for example the alert elements in Bootstrap 4 can also have Headings and paragraphs for the cases when you wish to display a bit longer web content ( more helpful hints).
