How can we make text to appear italicised?

The font-style CSS property sets whether a font should be styled with a normal, italic, or oblique face from its font-family.

font-style: normal;
font-style: italic;
font-style: oblique;
font-style: oblique 10deg;

/* Global values */
font-style: inherit;
font-style: initial;
font-style: unset;
