I appreciate all of those comments.
What I am finding out (and please let me know if this is totally wrong) is that adding a grid to a section is incorrect. For example: I have a basic section. Title on top, image on left, paragraph on the right. I have a large container, then I have three separate containers for each of those parts.
So, for the desktop I want it to be set up like that, but for tablet I want title, image, paragraph in that order. Same for the mobile. I guess what I’m looking for is how to make the responsiveness adaptive. So, if I adjust the breakpoints with the sliders, it will all scale smoothly and switch to how I need it to switch with the orders of things. If that all makes sense.
