GetPropertyCssValue() public method

Used to retrieve the object representation of the value of a CSS property if it has been explicitly set within this declaration block. This method returns null if the property is a shorthand property. Shorthand property values can only be accessed and modified as strings, using the getPropertyValue and setProperty methods.
public GetPropertyCssValue ( string propertyName ) : ICssValue
propertyName string The name of the CSS property. See the CSS property index.
return ICssValue 
        public virtual ICssValue GetPropertyCssValue(string propertyName)
        {
            if(styles.ContainsKey(propertyName))
            {
                SharpCssStyle scs = (SharpCssStyle)styles[propertyName];
                if(scs.CssValue == null)
                {
                    scs.CssValue = CssValue.GetCssValue(scs.Value, ReadOnly);
                }
                return scs.CssValue;
            }
            else
            {
                return null;
            }
        }
