Hello.

Answer 2

I did this:
For example, the image size is 1600x500
500/1600*100=31.25%
.bg{
background:url(images) center center;
background-size: cover;
padding-top:31%
}
This is if your block does not contain content, if there is content then position absolute for it and measure, or subtract content from padding as a percentage. If it's for body then you don't need padding at all.
Slightly stupid variak, but in a different way, I only wrote through js.
