Examples

Add type checking to --my-color {{cssxref('--*', 'custom property')}}, as a color, a default value, and not allow it to inherit its value:

Using CSS {{cssxref('@property')}} at-rule:

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

Using JavaScript {{domxref('CSS.registerProperty')}}:

window.CSS.registerProperty({
  name: "--my-color",
  syntax: "<color>",
  inherits: false,
  initialValue: "#c0ffee",
});
