The font-variation-settings CSS property provides low-level control over OpenType or TrueType font variations, by specifying the four letter axis names of the features you want to vary, along with their variation values.

/* Use the default settings */
font-variation-settings: normal;

/* Set values for OpenType axis names */
font-variation-settings: "XHGT" 0.7;

/* Global values */
font-variation-settings: inherit;
font-variation-settings: initial;
font-variation-settings: unset;

This works at an even lower level than font-feature-settings, which instead allows you to specify font feature tags and values.

Note: Whenever possible, Web authors should use other methods of controlling font display, like the font-variant shorthand property or an associated longhand property. This property is a low-level feature designed to handle special cases where no other way to enable or access an OpenType font feature exists.

This property can take one of two forms:

  • The keyword value normal
  • A <string> followed by a <number>. This may be repeated, with the <string> <number> tuples separated by commas.


Text is laid out using default settings.
<string> <number>
When rendering text, the list of OpenType axis names is passed to the text layout engine to enable or disable font features. Each setting is always a <string> of 4 ASCII characters, followed by a <number> indicating the axis value. If the <string> has more or fewer characters or contains characters outside the U+20 - U+7E codepoint range, the whole property is invalid. The <number> can be fractional or negative.
