CSS: Using Position Property

Absolute positioning of an element moving from the normal flow of the document

Box containing a paragraph

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec imperdiet erat pharetra libero malesuada rhoncus.

As you can see in this second example, the grey box has now been moved to the upper left corner of the page despite that in the HTML markup it continues to be found in the final part of the document.
