Can you explain what you're trying to do?

[thdoan]

Please see https://stackblitz.com/edit/vite-ps7x8w?file=docs%2Findex.md

I'm expecting there to be an external link icon similar to the link on the example page for consistency.

[brc-dd]

Ah, I see. For now you can do this:

---
layout: home

pageClass: external-link-icon-enabled

hero:
...

Thank you. Feel free to close as this option works for me.

[brc-dd]

No, we should fix it. Probably a 1-2 line change.

[thdoan]

Great. I assume once it's fixed, pageClass will be optional, right.

[brc-dd]

Yeah
