The goal of this epic is to track the migration of all the [bootstrap alerts](https://getbootstrap.com/docs/4.0/components/alerts/) in HAML and vanilla JS to GitLab UI. The Javascript removal is our priority, but we need to remove the CSS and replace it with the relevant GitLab UI styles too. To find these instances I used the following regex: | files | regex | | ------ | ------ | | `*.js` | `/\.alert\(/` | | `*.haml` | `/(\.\|class: '[^')]*)(?<!gl-)alert/` |
