The picture shows the standard start side of the Mikrotiks. Is it to be changed possibly this?

If you are oem system builder i say yes.. its possible

why? it's not your client interface...

This is right, however, this side I do not need, hence, I would have with pleasure another side.... Hence, also the question whether one can change this around with the Web-Proxy later only the IP to be able to brag.... Because HTML pages cannot be given with the Webproxy by own device...

if you don't need it, you can disable it in the services menu of RouterOS.

I can deactivate this side is clear to me. Only I would like to generate with pleasure another, own HTML page and indicate this by the call of the IP address. Is this not possible thus?

Do you want to log into it with your changed html?

if not, you could disable that page and have a firewall rule to re-direct you to another page that you make.

Many thanks for the answer. How would the fire wall rule have to look if I, e.g., on test.html site with appeal of my Interfaceip (e.g., 192.168.0.1) is escorted?
