As an example, consider the garamond font family, in its normal form, we get the following result:
@font-face {
font-family: garamond;
src: url("garamond.ttf");
}
The italicized version of this text uses the same glyphs present in the unstyled version, but they are artificially sloped by a few degrees.
On the other hand, if a true italicized version of the font family exists, we can include it in the src
descriptor and specify the font style as italic, so that it is clear that the font is italicized. True italics use different glyphs and are a bit different from their upright counterparts, having some unique features and generally have a rounded and calligraphic quality. These fonts are specially created by font designers and are not artificially sloped.
@font-face {
font-family: garamond;
src: url("garamond-italic.ttf");
font-style: italic;
}
