How can I embed the following adress in a Iframe or else

Hi, I a beginner in webflow and come from adobe muse.
I can’t embed the following adress:
http://www.sckh.de/spa/ma/index.html
so in the that it works.
Can someone help me to get the propper code?
Tks and regards
Siegfried

<iframe src="http://www.sckh.de/spa/ma/index.html" style="max-width:100%; max-height:80vh; width:100vw; height:30vw;"></iframe>

Thanks for your instruction. But at here it does not reach, to display the file!? (see screenshoots).
What can be the reason? Does it matter, that the domain ma-fa.de is SSL and the embeddet adress not?

What else can I do, to make it work.

Ah, you just have to load the https source instead like this https://www.sckh.de/spa/ma/index.html,

<iframe src="https://www.sckh.de/spa/ma/index.html" style="max-width:100%; max-height:80vh; width:100vw; height:30vw;"></iframe>

if it doesn’t work then you’ll have to contact the admin of sckh.de to request that they host their website over https.

Thanks,

it now werks perfect.

best regards
