CSS

The CSS interface holds useful CSS-related methods. No objects with this interface are implemented: it contains only static methods and is therefore a utilitarian interface.

Static properties

• CSS.highlights
  • : Provides access to the HighlightRegistry used to style arbitrary text ranges using the CSS Custom Highlight API.
• CSS.paintWorklet Experimental
  • : Provides access to the Worklet responsible for all the classes related to painting.

Instance properties

The CSS interface is a utility interface and no object of this type can be created: only static properties are defined on it.

Static methods

No inherited static methods.

• CSS.registerProperty()
  • : Registers custom properties, allowing for property type checking, default values, and properties that do or do not inherit their value.
• CSS.supports()
  • : Returns a boolean value indicating if the pair property-value, or the condition, given in parameter is supported.
• CSS.escape()
  • : Can be used to escape a string mostly for use as part of a CSS selector.
• CSS factory functions

  • : Can be used to return a new CSSUnitValue with a value of the parameter number of the units of the name of the factory function method used.

    CSS.em(3); // CSSUnitValue {value: 3, unit: "em"}
