            String stringValue = lu.getStringValue();

            if (stringValue.indexOf(" ") != -1) {
                //inline style property value that contain space must be single qouted
                if (isInline) {
                    stringValue = "'" + stringValue + "'";
                } else { //non inline css property value that contain space must be double qouted
                    stringValue = "\"" + stringValue + "\"";
                }
            }
