How to make svg zoom smoothly?

Question

JavaScript

The slider slider should increase/decrease as its position changes accordingly, ranging from 35px to 53px.
I roughly calculated that for each step he should add in size by 0.005, but I don’t know how to write a loop for this.

Answer 1

35+(53-35)*(ui.value/100)
But it's worth noting that your slider starts from 1 and in the minimum position it will not be exactly 35, but ~35.3px.
Just paste this formula everywhere instead of ui.value for width and height
