Hi Aakash,

Each browser has its own default styling for HTML elements. It's called the 'user agent stylesheet'. You'll learn about it in detail, and how to "reset it", if you keep following the course. In this particular case the top margin of the H1 pushes down the content box, thus creating the whitespace.

Hope it helps! Max
