@annotunzdy どのようにテキストを回転させるのですか?

@annotunzdy 1) why does this work?
2) why does this work on mastodon.social?

@usr_local_share
1) We improved [spin] tag on this instance (now.kibousoft.co.jp).

source code is here: github.com/kibousoft/mastodon/

2) This is feature of "Font Awesome".
Mastodon is currently using "Font Awesome" generally.
And, GNU OStatus protocol can share many html code.

@annotunzdy Good!

However, I do hope HTML in OStatus is secure enough, otherwise a hacker might set up a bad instance that would use XSS to steal users' sessions.

@annotunzdy but how the fsck does this work when displayed on my instance? If it's JS-based, does that mean that instances can inject JS into other instances in toots?

@rysiek It's CSS Animation of "Font Awesome". Not JS. And, mastodon is using Font Awesome.
