Answer 1

To change default theme to support BS5 - there is only one solution - to do it by rewrition the whole theme. It can takes from 2 to 5 wording days, depends on lyour skills level and knolage of BS3, 4, and 5.

Here you can read about migrations

Also there is a demo site I made, OpenCard 3 default theme but using BS5, and meny other modern libraries. https://fs3.focus.style/
