If you're doing class='centered' or class='with_padding', I don't see any reason not to just do style='align-self:center;' or style='padding: 1rem;' instead. The class names communicate less (Is that centering the content of the element, or the element itself? Is that vertical or horizontal centering, or both? Is the text being centered?). And it doesn't allow you to make sitewide changes like a semantic class does (You might want to change all .blog-title elements from centered to left-aligned, but do you really want to change all .centered elements from centered to left-aligned?). I'd go so far as to say this is an antipattern.
