/* Use the default settings */

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


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.
