This article was great! I think the overall premise is probably more useful for graphic designers than programmers, because I believe many programmers kind of implicitly know this advice. However I’ve worked with graphic designers in the past that were obsessed with having their Figma design translate to the web page in a pixel perfect manner, and they would always be confused when things didn’t align correctly. This inevitably leads to breakpoint Hell, where they design pixel perfect designs for tons of breakpoints and ask you to implement them.

While this is laudable, I think it’s important to remember that a design should focus more on how the layout flows when resizing the viewport and focusing on a couple target breakpoints. I think that’s what this article is trying to emphasize.
