What it means
A designed italic can differ substantially from its upright companion, especially in letters such as a and f. An oblique style is generally based more closely on slanting the upright forms, although naming varies between families. Both can create emphasis, but their tone and texture deserve inspection at the sizes you use.
Use it in practice
Use italics sparingly for a contrasting phrase, a title or a convention in your content. Load the intended italic style when it exists.
Watch out for
A synthetic slant from the browser may not match the designed italic. Long italic passages can also become tiring.
