I believe you mean <frameset>/<frame> rather than <iframe>s, though you used to be able to do frames inside iframes. I’m surprised mobile Safari supports them. Example: https://www.quackit.com/html/templates/frames/frames_example...

Wild! Every browser seems to support <frame> yet it's deprecated: https://caniuse.com/?search=frame

Ah yes you're right! Similar to iframes anyway.

Your example has `noresize` set, but I found one that doesn't: https://www.yourhtmlsource.com/examples/frameset1.html

It's not resizeable on mobile.

Yeah I mean, it was obsolete before the first iPhone so that's not surprising.
