There is no easy way to do that as template have few "break" point - when you resize browser widndow layout adapts to screen size and act responsively. Changing elements size will affect al steps and break layout when screen size is smaller.

Well , i know it's resize responsively... but, as i understand, those spaces are not a fixed number, but a percentage. So, for example, if I change this percentage, let's say, from 10% to 5 % the template layout will work the same way, but those spaces will be smaller... I'm i wrong ?
Thank you for your help

I see you have already made some changes by changing layout type in template settings - is that fit you better, or maybe you would like to correct it somehow?
