Bootstrap 5 Alerts Link Color class is used to set the color of the alert element. There are different kind of alerts that indicates different things, if there is a success then the color of the alert will be green, if it's a failure then it should show a red color alert. Each color of the alert represents something. Alert color should be its name, but we are using color on Alert Link so there will be a mixup with color according to the name on the documentation.
Prerequisite: Bootstrap 5 Alert Component, to create alert - for that we can use alert.

- alert-link: This class is used to make the text of the alert a link.
- alert-primary: This class is used to make the color of the alert blue.
- alert-secondary: This class is used to make the color of the alert gray.
