Understanding Responsive Design

Can anyone help me clarify this question? I am building my Figma design file before jumping on to Webflow and as I am trying to figure out how to scale my design down to fit different device viewports, this is confusing me:

If I need to scale down a section as a whole, with each element in proportion, and this means the scaled down type will no longer sit on the original type scale I created (because it’s just scaling in proportion to surrounding elements), is this ok? Is that how it’s done? Also, Figma doesn’t seem to scale the type. So how do I create my breakpoints with proportionally scaled down sections in Figma/Webflow? Thank you so much to the person who takes the time to answer this
