How to get away from absolute units if Inkscape draws in px by default (setting percentages doesn't change anything)?

How do I get away from absolute units if Inkscape draws in px by default (setting percentages doesn't change anything)?

Answer 1

If you don't want to learn the svg specification, then you can do this:
draw in your editor a 100 by 100 px svg. I drew in adobe illustrator.
Next, take this code and assign viewBox="0 0 100 100"
Here is an example with gradient, lines, rectangle, etc., it's scalable.
codepen.io/iiil/pen/FHChs
There are other ways. But there is no desire to understand your ton of code, I repeat, you need to start small, with one line, circle or rectangle. Remove all metadata from code and so on so they don't get in the way.
Here you can read about viewbox
