Kevin Powell makes wonderful content. I am saddened by the negative responses here. This article is a great intro for the absolute beginner to dip their toes into CSS.
It does make it kind of useful to write one line centers instead of two, but at the expense of people kind of needing to learn about damn logical properties when they read your code/blog.
Also, in my experience they interact with Flexbox and CSS Grid in useful ways that sometimes the "logical" properties are much easier to reason with than the 4-property versions or the individual property versions.
