The font-style property allows you to make your text
italic
or
oblique.
It can have one of the following four values:
normal
italic
oblique
inherit
If you set it's value to normal,
your text is displayed as normal, non-italic text (Note: this is also
sometimes referred to as the font's "Roman" or "upright" face).
If you set the font-style property to
italic, your text will be displayed in an italic face.
If you set it's value to oblique
your text will be displayed in an oblique face.
If you specify it's value as inherit,
your text will simply use the same font-style value as it's parent.
Tip:
This property is optional. If you would like to include it in your
generated CSS code simply check the checkbox by it's name (to enable it)
and choose a value for it from the font-style dropdown list.
