As more presentational html properties get deprecated the natural response for me was to make single property CSS classes such as .text-align-left{text-align:left}. My question is, is this preferred versus inline styles?

Stackoverflow actually uses quite a bit of inline styles.

PS: I know this isn't really a coding question and it is likely to incite debate but stackoverflow is the largest stack exchange for code and this question does have some use for future individuals.
