okay so, in view we have it like this. The multiple spaces inside the middle <p> block resolves to single in view.

@tiberiuichim @nileshgulia1 as the above screenshot shows that we have an empty rendered p tag. But due to margin collapse we didn't get the margin-top of the empty p tag and it is not solvable.
