How to increase block length depending on page length?

Question

HTML

Hello everyone The
question is very hackneyed, but Google's advice did not help to find a solution :(
The problem is that my page height is formed dynamically, depending on the number of elements on it. The elements are located one under the other and are formed by the script.
When I try to set the height body and html to 100%, then these blocks occupy only the visible part of the page, and the part below is not at all clear what this block is (at least the firefox inspector shows that body and html have nothing to do with it) I also tried to set values ​​in vh and vw units
plz
tell me maybe a screenshot will help explain a little better than me
