Yes tested and I found something. That is it may be the effect of css. Because I am using bootstrap .In my bootstrap has already uses an different style for the class "blockquote". In q2a site also uses the same class with different styles. I think this may the issue . But in previous the row style[ without using block quote] which I have inspected with fire bug it shows pre tag of each row, this is real unknown factor.
Please check and give reply
many thanks
