After ionic serve command I get this output:

Answer 1

If not using the Ionic framework, which includes it already, which is i think what vusan's answer is getting at, then Ionicons recommended usage is now:

1. Load its JavaScript in your app or page, https://unpkg.com/[email protected]/dist/ionicons.js
2. Use an ionic web component, <ion-icon name="warning"></ion-icon>

And all is happiness. Definitely better than the old fonts+classes way.

Answer 2

I got issue when using both from ionicons.com and /docs/ionicons/.
For alert icon, no need to use ionicons.com, use warning icon directly from https://ionicframework.com/docs/ionicons/

 <ion-icon name="warning"></ion-icon>

And remove including of ionicons.min.css on index.html (important)

So you will never have issues of wrong icon.
