I like the effort you put into this article. But I tend to do everything in REM valeus nowadays and not pixels as we live in a scalable vector based time I try to avoid PX as much as I can. For instance, i like to space elements on my websites with 1 REM in between. But i’m not a professional, I just started building websites a year ago. Is it actually still smart to use pixel values? Or is the use of REM not smart at all? I’d like to hear your point of view.
