All Implemented Interfaces:

java.io.Serializable, CSSPrimitiveValue, CSSValue, CSSValueList
```
public class CSSValueImpl
extends java.lang.Object
implements CSSPrimitiveValue, CSSValueList, java.io.Serializable
```
The CSSValueImpl class can represent either a CSSPrimitiveValue or a CSSValueList so that the type can successfully change when using setCssText. TO DO: Float unit conversions, A means of checking valid primitive types for properties
