This beats the point of using the SVG sprite, though. And makes the situation even worse for maintenance, see #39809.

We should streamline our icons usage and generally not try to fix StackBlitz if we are going to duplicate stuff and make maintenance harder.

Yes, considering the overall architecture of the documentation: the SVG sprite is better. However, it's probably less understandable to the end-user point of view for these examples in terms of autonomy and reusability (copy/pasting the code).

And makes the situation even worse for maintenance, see #39809.

I get your point about maintenance. For these use cases, maybe we don't necessary need these icons to be exactly the same as the final version of the ones in Bootstrap icons. Or maybe in Hugo we can make some of them reusable with partials (or anything else).

There's something to consider regarding the usage of the documentation by the users; the ease to understand, integrate into their projects and to create reproducible use cases when they create issues. I'm not saying I'm against your points, just that everything needs to be taken into account, not only docs' maintenance.

Since I don't have a strong opinion on the topic and I just would like these StackBlitz examples to be fixed, I let you decide with @mdo and @louismaximepiton which version would be better between this one and #39505, or any other strategies.

Note that if this one is closed, there's probably something to update in our Alerts documentation, because it's basically what's already done there.

It's one thing trying to make docs better and another make it harder for maintainers to maintain the docs.

The icons at this point are a mess. We have numerous icons everywhere, with no easy way to see what's used and what's not.

So, I'd rather have a few broken icons at the moment or just drop the StackBlitz examples from those than make the situation worse right now.

We need to figure out a simpler way to handle the icons before scattering more icons across the docs. Using the font in the examples is one easy way for us regardless the downside of people having to load the font. If someone wants to improve loading times later they could use the icons they only need to but that's covered in our icons documentation.
