In my experience the “one-off items” are far more common, simply because every one thing I do reuse will typically have several child elements. Why am I naming the styles that represent the title of a contact card if I never use it outside of the contact card—which itself is probably included by referencing a file called “ContactCard.html” or whathaveyou. Of course, there’s no right or wrong answer here, and I suspect it very much depends on what type of web systems you are building. I feel the entire debate is basically a special case of the question “do you make websites or web apps”.
