}

@property --property-name {
  syntax: "<color>";
  inherits: true;
  initial-value: #c0ffee;
}

Values

Using CSS @property at-rule:

css
@property --my-color {
  syntax: "<color>";
  inherits: false;
  initial-value: #c0ffee;
}

Using JavaScript CSS.registerProperty():

window.CSS.registerProperty({

  inherits: false,
  initialValue: "#c0ffee",
});
