Hi @doug :
You’d need to tweak your design for the different breakpoints (aka media queries in code speak… or more simply, the different devices/screen sizes/screen orientation). The grid help accomplish this, depending on your goal. Other times, using flexbox might be better. You just need to play around with it to understand what happens when you use each tool.
One thing I’ve found helpful is https://www.w3schools.com/css/ for understanding the theory of CSS. I also have a bit of a foundation in the code side of CSS, which makes it easier to understands the code and the theory behind the principles. While Editor X, Webflow, etc. are trying to shift from code-based CSS to visual-based CSS design with their tools, learning some CSS does help, and I’d recommend it. You could find free classes on youtube or pay for something on Udemy, which is pretty cheap.
Lastly, I’d recommend going to this live demo of the tool next week if you’re able. One of their product managers will be building a website, live to show you how things work together. I’m excited for this, because while Editor X Academy is helpful, you don’t get a great understanding of how everything works together.

Hope this helps!
