This is a very common programming axiom: "Don't Repeat Yourself".

It means you should avoid writing the same code lines multiple times when you can avoid it, often by making use of a function and/or loop. In this case, it's about making CSS rules apply to the same target(s).

The definition and example come from :hourglass: this point of the "max-width" video.
