Answer 3

Is it possible to set the font size other than in px?

It is possible and not only in%, there are a bunch of other units: pt, vh, vw, vmin, vmax, em, rem, etc.
only through js. The calculation is based on the base font size. There is an option with vh and sometimes it helps if the height of the block depends on the height of the window or vice versa, then sometimes you can calculate the font size in this way and specify it in vh. But that's the way it is.

Answer 4

Developing the idea Maxim Timofeev
Set a block of fixed proportions and set the font size to vh.

But it really works so-so.
When you change the height is normal, when you change the width everything floats.
