<p><b>Note:</b> Even if the content of the relatively positioned element is moved, the reserved space for the element is still preserved in the normal flow.</p>

question:
is there a way to avoid the reserved space
because I dont want a large whitespace

Answer : avoid the reserved space

If you use absolute positioning then you can move the element around wherever you like and it will not have any reserved white space. Essentially, the element is removed from the flow of the document.
