Thefont-style
CSS property sets whether a font should be styled with a normal, italic, or oblique face from its font-family
.
Italic font faces are generally cursive in nature, usually using less horizontal space than their unstyled counterparts, while oblique faces are usually just sloped versions of the regular face. When the specified style is not available, both italic and oblique faces are simulated by artificially sloping the glyphs of the regular face (use font-synthesis
to control this behavior).
font-style: normal; font-style: italic; font-style: oblique; font-style: oblique 10deg; /* Global values */ font-style: inherit; font-style: initial; font-style: unset;
The font-style
property is specified as a single keyword chosen from the list of values below, which can optionally include an angle if the keyword is oblique
.

. If no italic version of the face is available, one classified as oblique
is used instead. If neither is available, the style is artificially simulated.oblique

<angle>
oblique
, and additionally specifies an angle for the slant of the text. If one or more oblique faces are available in the chosen font family, the one that most closely matches the specified angle is chosen. If no oblique faces are available, the browser will synthesize an oblique version of the font by slanting a normal face by the specified amount. Valid values are degree values of -90–90 inclusive. If an angle is not specified, an angle of 14 degrees is used. Positive values are slanted to the end of the line, while negative values are slanted towards the beginning.Variable fonts can offer a fine control over the degree to which an oblique face is slanted. You can select this using the <angle>
modifier for the oblique
keyword.
For TrueType or OpenType variable fonts, the "slnt"
variation is used to implement varying slant angles for oblique, and the "ital"
variation with a value of 1 is used to implement italic values. See font-variation-settings
.
For the example below to work, you'll need a browser that supports the CSS Fonts Level 4 syntax in which font-style: oblique
can accept an <angle>
.
<header> <input type="range" id="slant" name="slant" min="-90" max="90" /> <label for="slant">Slant</label> </header> <div class="container"> <p class="sample">...it would not be wonderful to meet a Megalosaurus, forty feet long or so, waddling like an elephantine lizard up Holborn Hill.</p> </div>
