Speaking of utility libraries, Jeremy Keith responded to Adam Wathan's article that we linked to not long ago. Jeremey is with him through the first four "phases", but can't come along for phase 5, the one about going all-in on utility libraries:
At this point there is no benefit to even having an external stylesheet. You may as well use inline styles. Ah, but Adam has anticipated this and counters with this difference between inline styles and having utility classes for everything:
You can’t just pick any value want; you have to choose from a curated list.
Right. But that isn’t a technical solution, it’s a cultural one. You could just as easily have a curated list of allowed inline style properties and values. If you are in an environment where people won’t simply create a new utility class every time they want to style something, then you are also in an environment where people won’t create new inline style combinations every time they want to style something.
I think Adam has hit on something important here, but it’s not about utility classes. His suggestion of “utility-first CSS” will only work if the vocabulary is strictly adhered to. For that to work, everyone touching the code needs to understand the system and respect the boundaries of it.
