 // Valid values for both shape-inside and shape-outside. Two values are specified when the shape property value
 // differs from the specified value. Three values are specified when the computed shape property value differs
 // from the specified value.
 // eg: "specified value/CSS Text value/computed style value"
 // or: ["specified value", "CSS Text value/computed style value"]
 // or: ["specified value", "CSS Text value", "Computed style value"]
