A key-value style pair associating a CSS property with a value.

Usage Notes

The following examples create animation styles that collect a set of CSS property values:

          // string values for CSS propertiesstyle({ background: "red", color: "blue" })// numerical pixel valuesstyle({ width: 100, height: 0 })

The following example uses auto-styling to allow an element to animate from a height of 0 up to its full height:

          style({ height: 0 }),animate("1s", style({ height: "*" }))
